Week 14 – your 2nd trimester

Hopefully you are starting to feel less tired and sick now. As your energy levels return, your appetite might too. Remember, your baby does not need any extra calories at this point. Too much weight gain in pregnancy is not good for you or the baby. If you get hungry between meals try sticking to healthy snacks.
What's happening in my body?

The placenta is 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 do not mix. That's because you might be different blood groups, and mixing them up could be dangerous.

Remember to talk

Relationships can come under strain when you're pregnant, due to all kinds of worries. Talk about your feelings and speak to your doctor or midwife if you feel like you're not coping. Tommy's has advice on relationships and pregnancy.

Colostrum

You may notice some yellow stains in your bra – this is probably colostrum, which is the first milk you will produce. Ask the doctor or midwife to have a look if you're worried about any changes.

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! 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.
