At 9 weeks, you’re now in month three of your pregnancy, and your second trimester is just around the corner.
9 weeks pregnant: pregnancy symptoms and your baby’s development
Explore pregnancy stages week by week
9 weeks pregnant is how many months?
Month 3 (Trimester 1)
At 9 weeks pregnant, your second trimester is getting closer, and the first weeks of your pregnancy come to an end. If you’re experiencing any 9 weeks pregnant symptoms, you might feel less than your best. However, the good news is that many pregnant women feel much better and more energised from the second trimester - not long to go now!
Your baby’s development at 9 weeks pregnant
Babies at 9 weeks have a lot going on when it comes to their growth and development in the womb. Their internal organs, including their heart, brain, kidneys, lungs and digestive system, continue to develop, and their mouth and tongue have started to form - your baby even has tiny taste buds1.
By now, your baby is starting to move around, but it’s unlikely that you’ll be able to feel these movements for a few weeks2. If you choose to have a private scan, you might be able to see your baby moving on the screen.
As you near the end of your first trimester, the placenta will start taking responsibility for producing pregnancy hormones, most notably progesterone3.
How big is my baby at 9 weeks pregnant, and what do they look like?
At 9 weeks pregnant, your baby is approximately the size of a strawberry or cherry and measures approximately 22mm from their head to their bottom1.
Your baby is starting to look a little more human now as their face starts to take shape and their features are becoming more defined. Their eyes are getting bigger, and, even at 9 weeks pregnant, contain some colour pigment. Your baby’s limbs are growing more daily, and their hands and feet have ‘grooves’ which will soon become their fingers and toes1.
This week your baby’s genitals start to develop. If you’re eagerly waiting to find out if your baby is a boy or girl, you’ll have to wait a little longer, as it’s still too early to see this on an ultrasound. You’ll usually be able to find this out at your 20-week scan.
What’s happening in my body at 9 weeks pregnant?
At 9 weeks pregnant, the pregnancy hormone, human chorionic gonadotropin (hCG) is also at its highest level, as the amount in your body doubles every few days1. hCG is a very important hormone, as it stimulates progesterone production, which will help maintain and support a healthy pregnancy4.
In addition to the hormonal changes, your breasts are likely to have grown bigger by the time you reach week 9 of your pregnancy. Investing in a supportive maternity bra may help you feel more comfortable.
Early pregnancy symptoms at 9 weeks
You might be experiencing a number of 9 weeks pregnant symptoms by now, many of which are due to those hormonal changes and the increase in your hCG levels.
Let’s look at some of the signs of pregnancy at 9 weeks.
As your breasts become larger, they may become sore and tender, and you might also experience a tingling sensation. Once again, this is all down to those pregnancy hormones5. You may also notice that your nipples become darker and stand out more, and that the veins in your breasts are more visible6.
To ease any discomfort, you could try:
- Having a warm shower or bath.
- Putting a cold compress on your breasts.
- Wearing a supportive maternity bra.
Tiredness and fatigue are common features of early pregnancy, and they can leave you with a lack of energy at 9 weeks pregnant. Whilst it might be easier said than done, particularly if you’re working and/or looking after older children, it’s important to try and rest when you need to.
Many women find that their tiredness and fatigue start to subside as they enter their second trimester. This could partly be because the placenta is fully formed at 12 weeks, taking over some of the vital jobs your body has been doing to maintain a healthy pregnancy7.
Around 8 out of 10 pregnant women experience nausea and vomiting during their pregnancy8, and this is more commonly known as morning sickness. Don’t be fooled by the name, though! Whilst many women find that their symptoms are worse in the morning, nausea and vomiting can occur at any time of the day9.
Morning sickness is thought to be caused by hormonal changes in your body, but many women find that their symptoms ease during their second trimester (usually between 16 and 20 weeks pregnant)9.
As your body continues to be affected by the increase in pregnancy hormones, progesterone in particular can leave you feeling bloated and gassy. Progesterone helps the muscles in your womb relax, making room for your baby as they grow. In the process, it can also relax the muscles in your digestive system, resulting in excess gas that can leave you feeling bloated10.
In most cases, some light spotting or bleeding during early pregnancy is nothing to be concerned about. It’s usually the result of something called ‘implantation bleeding’ when the embryo embeds into the lining of your womb. It can also be a result of changes to your uterus that can cause some light bleeding11. If you experience any bleeding at all during your pregnancy, you can contact your Early Pregnancy Unit and speak to someone for advice.
It’s also possible that you’ll experience some mild cramping at 9 weeks pregnant, as your muscles and ligaments continue to stretch, or if you’re experiencing trapped wind or constipation12.
If the pain becomes severe or the bleeding becomes heavy, speak to your doctor or midwife for advice.
At 9 weeks pregnant, you may be heading to the toilet for a wee far more often than usual, as your growing baby puts more pressure on your bladder6.
Due to the hormonal changes and increases in your body, you may experience mood swings. Taking care of yourself is essential, and as well as making sure you’re talking to your friends and family, you could try:
- Eating a healthy balanced diet.
- Rest as and when you need to.
- Some gentle exercise if you feel up to it.
Becoming a parent is a big life change, and it’s not unusual to experience several different feelings and emotions. However, if you have any concerns about how you’re feeling at 9 weeks pregnant, or at any point during your pregnancy, don’t hesitate to seek advice from your doctor or midwife.
9 Weeks Pregnant: Next Steps
At 9 weeks pregnant, you’re getting ready to enter your second trimester, and there are a few things to think about and prepare as you get ready to meet your baby.
Time to make it official?
It’s entirely up to you when you decide to tell people around you that you’re pregnant. While some women prefer to wait until they reach the second trimester, or until after their first ultrasound scan, others prefer to tell those closest to them straight away.
If you’re in employment, you’re not obligated to tell your employer about your pregnancy until at least 15 weeks before your due date (this works out at around 6 months). However, you may feel it’s better to tell them sooner than this to enable your employer to carry out the necessary risk assessments to keep you safe at work.
Preparing and eating food safely during pregnancy
Your body experiences many changes during pregnancy, your immune system function being just one of them. As your baby grows in your womb, your immune system becomes weaker so that your body can prioritise the health of your pregnancy14.
This can leave you more vulnerable to infection, so it’s important to take extra care with food preparation and hygiene to avoid food poisoning. Here are our top tips:
- Wash all surfaces and any utensils you intend to use before preparing food.
- Wash your hands in hot, soapy water before and after food preparation.
- Wash your hands thoroughly before and after handling raw meat, poultry, fish and seafood. This also applies when handling raw eggs.
- Store raw foods away from cooked foods.
- Thoroughly wash all vegetables, fruit and salad items. These items can contain soil traces and bacteria that can be harmful to your unborn baby.
- Avoid eating any food that has gone past its sell-by date.
- Ensure your food is piping hot throughout, especially sausages and whole cuts of meat.

9 weeks pregnant: FAQs
How much weight should I gain during pregnancy?
How much weight you’ll gain during pregnancy will depend on many things, including your pre-pregnancy weight. It’s difficult to know exactly how much weight you’ll gain, but on average, most women gain between 10kg and 12.5kg (22–28lb)15.
Most weight gain occurs after week 20 of pregnancy and is due to your rapidly growing baby and your body storing fat in readiness for breastfeeding15.
What supplements and prenatal vitamins should I take at 8 weeks pregnant?
Eating a healthy, balanced diet should provide most of the nutrients, vitamins and minerals you and your baby need during pregnancy. However, in addition to that, there are some prenatal vitamins and supplements that healthcare professionals recommend you take. These are13:
- Folic acid is an essential prenatal vitamin that helps reduce the risk of spina bifida and supports your baby’s neural tube as it develops into their brain and spinal cord. Pregnant women should take 400 mcg every day.
- 10 mcg of vitamin D.
What can I do if I feel faint during pregnancy?
The hormonal changes going on in your body can cause you to feel faint from time to time. If this happens to you, try16:
- Sitting down and resting until the feeling passes.
- Getting up slowly if you’ve been sitting or lying down.
- Sleeping and resting on your side and avoiding sleeping on your back.
It can also help to drink plenty of fluids to stay hydrated.
What should I be feeling at 9 weeks pregnant?
There’s no way to tell how you’ll feel at 9 weeks pregnant, or at any point in your pregnancy journey. However, it’s worth bearing in mind that the levels of oestrogen and progesterone in your body will be high at this point in your pregnancy, as the blood supply to your womb increases1.
As a result, many women at 9 weeks pregnant describe experiencing a ‘rollercoaster’ of emotions, and switch very quickly between feeling happy and sad.
Is week 9 the hardest week of pregnancy?
That all depends on your own experience. For some women, week 9 can bring a whole host of pregnancy symptoms such as morning sickness, bloating and fatigue. For others, these might be starting to ease as they head into the second trimester.
Always keep an eye on how you’re feeling and seek support when you need it.
What are the odds of miscarriage at 9 weeks?
Early miscarriages are those that happen during the first 12 weeks of pregnancy. The risk of miscarriage decreases as your pregnancy progresses, and one study showed that the risk of pregnancy was 0.5% at 9 weeks, reduced from 9.4% at week 617 in the women taking part.
If you have any concerns about how your pregnancy is progresses, be sure to have a chat with your doctor or midwife.
Will I have a dating scan in week 9 of pregnancy?
You won’t be routinely offered a 9-week scan during pregnancy, although your first ultrasound (also known as your dating or 12-week scan) can be offered anywhere between 10 and 14 weeks18.
If you’ve had complications in a previous pregnancy, or if you’re experiencing pain or bleeding, you may be offered an early pregnancy scan to make sure that your pregnancy is progressing as it should19.
