Week 14 – your second trimester

Welcome to week 14! You're probably feeling more like yourself again now, after the tricky first trimester. As your energy soars, you may find that your appetite does too… but take it easy. Your baby doesn't need any extra calories now, and too much weight gain in pregnancy isn't good for you or the baby. If you get hungry between meals then ditch the crisps and top yourself up with super snacks that will give you a healthy boost.

What's happening in my body?

It's 'all systems go' inside your pregnant belly. There's still a lot more growing to do, but everything's in place.

You have an extra organ in your body that wasn't there 14 weeks ago, and that's the placenta. The placenta is pancake shaped – the word placenta means 'flat cake' in Latin. It's full of blood and pumps out nutrients, oxygen and hormones, while removing waste products such as carbon dioxide. The placenta is firmly attached to your womb and links up with your baby through the umbilical cord.

Your blood and the baby's blood come into close contact in the placenta – but they won't ever mix. That's because you might be different blood groups, and mixing them up could be dangerous. Your body's thought of everything!

Love, love, love

Make love, not war with your partner. Relationships can come under strain when you're pregnant, due to all kinds of financial and practical worries. You might start arguing about big things, like sex and money, and smaller things, like whose turn it is to put out the recycling (not yours, you shouldn't be lugging anything around during pregnancy!). Talk about your feelings and involve your partner as much as possible at scans and antenatal classes. Tommy's, the baby charity, has more advice on relationships and pregnancy.

Busting out

Many women love it when their breasts get bigger. However others hate the extra weight, as it gives them backache, and swollen breasts can be painful. You could also get stretch marks and big blue veins. As usual, your hormones are to blame, along with the extra blood that's now circulating around your body.

Keep an eye out for any yellow stains in your bra. This is probably colostrum, which is the first milk produced by mums-to-be. It's telling you that your breasts are raring to go, so go with the flow. If it's a problem, then start using breast pads.

Ask the doctor or midwife to have a look if you're worried about any changes. Don't be embarrassed – they've seen breasts before!

Second trimester pregnancy symptoms (at 14 weeks)

Hopefully you're looking and feeling much better now. That first trimester really was a slog, wasn't it? However you may still be getting a smorgasbord of symptoms. Your signs of pregnancy could include:

Tommy's, the baby charity, has a further list of common symptoms.

What does my baby look like?

Your baby, or foetus, is around 8.5cm long from head to bottom, which is the size of a kiwi fruit. The head is getting rounder and more in proportion with the rest of the body. Your baby is kicking around, but you probably won't feel it yet. However your midwife might be able to hear the heartbeat, using a handheld monitor placed on your tummy.

Inside you, your baby is doing something quite miraculous – having a wee! This might not seem impressive, but it's a first for them! Small amounts of the amniotic fluid are swallowed by the baby and pass into the stomach. The kidneys then kick in and the fluid is passed back out again as urine. Round of applause please!

Action stations

This would be an excellent week to tick off a few of these jobs…

Many women will tell their employer after they've had their first pregnancy scan at around 12 weeks. Once you tell your employer, you have maternity rights and can attend antenatal appointments during paid work time. You can also ask for a risk assessment of your workplace to ensure that you're working in a safe environment.

It's a good time to tone up those muscles 'down under'. Gentle exercises can help to prevent leakage when you laugh, sneeze, cough or jump around on your future baby's trampoline. Get the muscles going by pretending that you're having a wee and then stop the 'urine' in midflow. Visit Tommy's for more ideas about pelvic floor exercises.

Ask your midwife or doctor about antenatal classes in your area, as they get booked up very quickly. You could also contact your local branch of the National Childbirth Trust. Why not ask your partner to go with you? Even if you've had children before, and been there, done that, they're still worth going to, as you can meet other parents-to-be. Also don't expect this pregnancy to be just like your others – your baby could have other ideas.

Do your best to stop smoking, give up alcohol and go easy on the cappuccinos. We know that's easy to say but hard to do. Ask your midwife or GP for support.

During the winter, consider taking a daily dose of vitamin D, the sunshine vitamin. It's recommended that you take 10 micrograms every day when you're pregnant and breastfeeding. Find out if you're entitled to free vitamins.

Get moving! It's recommended that pregnant women do 150 minutes of exercise throughout the week. You could start off with just 10 minutes every day. Perhaps take a brisk walk in the park or go for a swim. If you start any classes, make sure the instructor knows that you're pregnant. Don't overdo it though – listen to your body.

Don't eat for two! Eat for you. You don't need any extra calories until the third trimester, which starts in week 28. Try to eat healthily, with plenty of fresh fruit and veg, and avoid processed, fatty and salty foods. You may be able to get free milk, fruit and veg through the Healthy Start scheme.

This week's treat

There's always so much to do isn't there? However this week, on your 'to do' list, add the word 'relax'. Find some music that makes you feel peaceful and listen to it. Some mums listen to music when they're giving birth, so why not start picking out a playlist now? There's no strong evidence that music can alleviate pain, but it could help to keep you calm.
