At three months pregnant, you're about to enter the second trimester, and some of the early pregnancy symptoms you might still be experiencing could soon start to subside.

Read on to learn more out what's happening inside and outside your belly at three months pregnant.

Common Pregnancy Symptoms at 3 Months Pregnant

At three months pregnant you may still be experiencing some of the symptoms of early pregnancy, and there's a chance of some new ones cropping up too.

Some of these symptoms can be quite challenging at times. Keep in mind that you may not experience them all.

  • Increased vaginal discharge. You may experience a little more vaginal discharge than usual when you're pregnant. As long as it's thin, clear or milky white, and doesn't smell bad, this is probably nothing to worry about. Tell your doctor or midwife if your discharge smells strange or unpleasant, or if it's green or yellow, especially if you have itching or soreness around the vagina or if it hurts when you pee. These could be signs of a vaginal infection. A cottage cheese-like discharge with no smell could be thrush, a common yeast infection. Your doctor or midwife can advise you on how to treat thrush safely during pregnancy.

  • Nausea. If you've been experiencing morning sickness in the first trimester, then you may still be feeling queasy at three months pregnant, but the end of this particular symptom could be in sight now: In most cases, morning sickness clears up sometime in the second trimester. In the meantime, you could try and alleviate the symptoms by staying hydrated, getting plenty of rest, avoiding foods or smells that trigger nausea, and eating small frequent meals of food that are high in carbohydrates and low in fat. Eating food or drinks containing ginger may also help ease nausea and vomiting (although you should check with your doctor, midwife or a pharmacist before taking ginger supplements while pregnant).

  • Skin changes. Those hormones coursing around your body at the moment can cause changes to your pigmentation. As a result, your skin may get a little darker, either in patches or all over. Your nipples and the area around them may also darken, and so could any birthmarks, freckles or moles that you already have. Most of these changes usually fade away gradually after your baby is born, although your nipples may stay a little darker even after childbirth. When you're pregnant, your skin can be more sensitive to the sun, making you burn more easily. This means it's important to use a high-factor sunscreen, and avoid spending too long in the sun.

  • Thicker, shinier hair. Not all the symptoms of pregnancy you might be experiencing at around three months pregnant are unpleasant. Many mums-to-be find that the rush of hormones they get during pregnancy gives their hair extra body and a luxuriant sheen. If this happens to you, enjoy this ‘fringe benefit' of being pregnant while it lasts!

  • Breast changes. At around three months pregnant, the size and shape of your breasts could be changing around now. This is partly in response to the development of the milk ducts that will eventually supply nourishment to your newborn baby if you breastfeed. Breast changes vary a great deal between mums-to-be, but it's possible that your breasts will feel heavier, and your nipples may also be more sensitive. Now might be a good time to go shopping for a more comfortable bra. Why not treat yourself to a professional fitting at one of the major high-street clothing chains or a specialist lingerie shop?

What’s Going on in Your Belly at 3 Months Pregnant?

At three months pregnant your little one is now fully formed, with all his or her organs, muscles and bones in place, but there’s still plenty of growing and developing left to do before it’s time to leave the comfort and safety of your belly.

At this stage the bones are still made of relatively soft cartilage, but they’re now starting to harden into proper bone.

Although your little one’s head is still very large, now that you’re three months pregnant the rest of his or her body is growing fast and straightening out, giving your foetus more baby-like proportions with every week that passes.

Soon you may get the chance to see for yourself what’s going on inside your belly, at your first ultrasound scan. This is usually offered between 8 weeks and 14 weeks.

A photo of your first scan is a fantastic keepsake. Sharing it via social media, email or the post can be a great way of announcing your pregnancy to friends and family.

It’s a good idea to ask your hospital in advance about its policy on printing off photos or videos of ultrasound scans, and any extra charges this might entail.

3 Months Pregnant: Your Body’s Changes

You might start to show a little baby bump sometime soon, but when this happens varies a lot between mums-to-be. Don’t feel left out if you still don’t look as pregnant as you might be feeling right now – it’s only a matter of time.

By the way, an important change takes place inside your belly at around three months pregnant. Until now or until very recently, your little one was nourished by the yolk sac that has surrounded your foetus from the very beginning.

Now, a brand new organ called the placenta is fully formed and ready to take over the job of supplying oxygen and nutrients to your growing foetus, if it hasn’t done so already.

The placenta’s great trick is that it can transfer everything your little one needs from your blood to the foetal blood, without the two sets of blood actually coming into contact with each other.

Your foetus will get all this good stuff via the umbilical cord, which will also be responsible for removing waste products.

How Far Along Am I at three Months Pregnant?

If you’re wondering how many weeks along you are at three months pregnant, there’s no standard answer to this because weeks don’t fit neatly into months.

As a rule of thumb, though, three months pregnant is often defined as covering week 9 through to week 13, so you’re probably coming up to (or already in) the second trimester of your pregnancy around now.

FAQs at a Glance

  • You won’t usually be able to feel your foetus moving yet at three months pregnant. This usually happens sometime between 16 weeks and 24 weeks of pregnancy. Those first movements will probably feel like a gentle swirling or fluttering in your belly.

  • At three months pregnant, your waist may be a little thicker and you might notice your belly sticking out a little more, although it could still be a while before other people start noticing and commenting on its size.

    Every pregnancy is different though, and a lot depends on your physique. Also, keep in mind that first-time mums-to-be usually start showing a bit later. So, don’t worry if your baby bump isn’t visible just yet – it won’t be that long before your belly becomes impossible to ignore!


    At three months pregnant some of the symptoms of early pregnancy may be about to ease up. The second trimester is known as the ‘honeymoon period’ of pregnancy, and you may even start to feel the energy boost that can start to kick in around now.

    Some of the symptoms you may be experiencing at three months pregnant include:

  • You won’t usually be able to know the sex of your little one until your second ultrasound scan, which is usually offered at between 18 weeks and 21 weeks. Even then, it’s not always possible to tell for certain.

    If you’re planning to ask your foetus’s gender at your next scan, check out some of these creative gender reveal ideas for some fun ways of sharing the news with your family and friends.

Checklist for When You’re 3 Months Pregnant

  • Consider sharing the news with your friends and family. Take a look at these fun pregnancy announcement card ideas for some inspiration.

  • If you work, ask your employer for detailed information on your maternity rights and entitlement to maternity pay and leave. Your partner could also be entitled to paternity leave.

  • Start bonding with your little one right now, at three months pregnant, by talking or singing to your bump, or by listening to your favourite music. It won’t be long before your foetus is able to hear your voice from inside your belly.

  • Pregnancy is a magical experience, but it can also be stressful and worrying at times. Talk to your partner, friends or family if you’re feeling anxious, vulnerable or just a little down. If you feel there’s nobody to confide in, your midwife or doctor can also point in the direction of support groups or professional help in your local area.

  • Speak to your doctor or midwife about safe exercise options that might be suitable for you while you’re pregnant.

  • Start doing pelvic floor exercises, if you haven’t already. These simple muscle clenches are a great way of preparing your body for labour and delivery. They may also help you recover more quickly after the birth. Even better, you can do them anywhere, anytime, without anyone else noticing.
