7 weeks pregnant: symptoms, advice and what to expect

Section: Week by Week

✅ Medically reviewed by Dr Helena Watson on 6th June 2020


At seven weeks pregnant your belly might not be showing but you’ll start to get some different symptoms and the beginning of that pregnancy glow (get ready for the compliments). Not only is your skin looking better than ever, your hair is more lustrous than that time you spent a fortune on Moroccan oil. These are both down to the extra oestrogen you’re producing right now.  

At the moment, your little baby growing inside you is your little secret and while you know exactly what's going on inside you, those around you will have no idea! 

In this article: 

In terms of months (although the doctors prefer to refer to weeks) you are one month and about two weeks pregnant. 

Your pregnancy bump won’t be showing yet, because your womb still hasn’t risen (it won’t do until the end of the first trimester), but that doesn’t mean you’re not feeling the full effects of being pregnant.

From nausea to the swollen breasts, your body is getting ready to grow your little one!

What size is my baby at 7 weeks pregnant?

The fetus now measures about 1cm (or half an inch), which is about the size of a blueberry and will start making his or her first movements this week.


What’s my baby doing?

Let’s take a look at your little blueberry at week seven.

Your baby at this stage will have a more defined face, with a mouth, nostrils, ears, and eyes. Simultaneously, brain cells are generating at the rate of 100 per minute with their head growing faster than the rest of their body to make room for all those brain cells. 

The mouth, tongue, tooth buds will also develop this week.

Your baby at 7 weeks

This week your baby will start to form cartlidge to make their arms and legs, dividing into the hand, arm and shoulder segments and leg, knee and foot segments.

Yet right now, they’ll still look like paddles more than hands and feet, as fingers and toes will be webbed.

Your baby now has kidneys that are ready to start work, as pretty soon your baby will start producing urine.

Your baby is also starting to make little jerky movements this week. You won’t be able to feel a thing, but an ultrasound would pick it up.

Most amazing of all, your baby now has its own rhythmic heart beat!



8 common symptoms you might be experiencing at 7 weeks pregnant

According to Milli Hill, founder of The Positive Birth Movement and mum of three, the not-so-nice symptoms will now be setting in. 

'As you get further into your first trimester, you may find you begin to experience a range of new feelings and symptoms, from the less glamorous - such as bloating, constipation and indigestion - to the more mysterious - such as cravings, a heightened sense of smell and a new tendency to sob during cheesy TV dramas,' says Milli.

1) Frequent urination

You’re still needing to pee every five minutes thanks to that pregnancy hormone hCG increasing the blood flow to your pelvic area.

Remember to keep drinking despite those constant toilet trips – your body and your baby needs it!

2) Fatigue

Growing a baby is an exhausting task, especially as your body is still making the placenta, so listen to your body and rest up.

One way to keep your energy up is to keep snacking throughout the day – mini-meals will keep your blood sugar up.

3) Breast tenderness and changes

Despite looking bigger than they’ve ever done (some women have gone up a full cup size by seven weeks pregnant), your boobs might not look their best! Noticing loads of blue veins? Of course, you can thank those pesky pregnancy hormones for that. 

These veins will transport all the nutrients and fluids to your baby when you begin breastfeeding.

You might also notice the areola (the dark area around the nipple) has got darker and larger and has little goose-bump-like spots. These are sweat glands that supply lubrication – all-important changes for when you start breastfeeding.

For now, invest in a good stretch mark cream and maternity bra to minimise sagging.

4) Excessive saliva

Feel like you’re dribbling? Just when you thought the morning sickness was bad enough, pair it with excessive saliva and you’re in for a treat.

Another one that will disappear at the end of your first trimester, but for now, try chewing sugarless gum.

5) Food cravings

If you find you’ve narrowed down your menu of meals thanks to those pregnancy food aversions, try not to worry.

Eating the same healthy meal every day will still give your growing babe all the nutrients it needs.

What’s more, if you find your cravings are driving you mad, give in to them once in a while.

6) Heartburn

Another totally normal, but totally unpleasant side effect. Avoid spicy or fatty foods, caffeinated drinks as these will make it worse, also try drinking either before or after you eat.

7) Gaining a few pounds

You might not look like you’re carrying a baby, but you might have gained a few pounds already. This is totally normal – most women will gain 25-35 pounds during pregnancy.

8) Cramping

This is normal during the first trimester, but if it occurs with shoulder or neck pain, or you have any unusual discharge, contact your GP.


What should I be doing this week?


Are you bleeding?

One thing you must look out for is bleeding, whether this is in the form of light dotting or spotting, pink discharge or lots of blood. 

Bleeding in the first trimester is very common (it affects around one in three women) and doesn’t always indicate a miscarriage.

If you do notice bleeding, you must see your doctor right away. Your GP or midwife will be able to examine you both vaginally and probably via an ultrasound.

In most cases, the bleeding goes away and the doctor is unable to explain it unless it’s caused by infection.

Your belly at seven weeks pregnant

You can try and make yourself look like you have a bigger bump all you like but most mums-to-be won't be showing yet as your tot is still so tiny. You can expect plenty of bloating however that may make you feel like you have your bump. 


Let them take care of you...

'Now is the time to rest,' says Milli. 

'Listen to your body. It's doing something completely amazing. And listen to your mind. It's probably working overtime, too - there's a lot to take in. Try to really mother yourself with lots of nutritious meals, early nights, and plenty of whatever makes you feel calm and nurtured. Pay attention to your emotions and your mental health, too, and seek extra support if you need to.' 

You’re going to be feeling fatigued, bloated and sick so this is the time to be selfish. 

Let your friends, family, and your partner be aware that you need some support about now.

It's time to know your exercise do's and don'ts


There is a lot of scaremongering around exercising while pregnant, but keeping fit and active has been shown to help make your whole pregnancy and labour itself much easier. Still, there are a few things you should try to avoid while you're at it:

  1. Don't exercise on your back.
  2. Don't hold your breath while you exercise.
  3. Don't use twisting motions.
  4. Don't challenge your sense of balance or risk any sort of trauma to your abdomen.

Many people don't realise that the health of your mouth is important to keep checking while you’re pregnant.

Go to the dentist so your oral hygiene and routine can be looked at. 


Boost your folic acid levels 


As your baby is growing so fast during this period, it's a great time to start taking folic acid as it can help prevent defects in your babies development. You can take it through supplements or natually through food such as nuts and breakfast cereal high in folic acid. 

Here are nine healthy foods high in folic acid.
