Week 17

Your baby’s internal organs, such as the digestive system and lungs, are developing and maturing. Baby’s eyes are still closed, but they can move from side to side. Your baby already has tiny individual fingerprints and a firm grip. This is a very special time during your pregnancy, when you are likely to be feeling fit and well, healthy and active. You’ve got a definite bump and are beginning to believe you really are pregnant (you may even have to start wearing pregnancy jeans!).

Your body

Your heart and kidneys are working harder now, pumping lots of extra blood around to bring nourishment and oxygen to your baby. Your digestive system has quite a bit less space than it used to, however, so it might become more sluggish, resulting in heartburn, indigestion or constipation.

The best way to steer clear of these problems is to drink plenty of caffeine-free fluids – at least eight 8-ounce glasses a day - and eat lots of fibre-rich foods, like fruit, veg and wholegrain carbs. Organic fruits and vegetables are a great choice, with lots of fibre and no harmful pesticide residues.

Avoiding illness

During your pregnancy, your immune system is also under extra pressure. If you do become unwell, try to avoid taking any unnecessary medication; if you're not sure whether something is safe to take, ask your doctor or pharmacist for advice.

It's also a good idea to avoid contact with children who have chickenpox (if you haven’t had it yourself) and measles (if you haven’t been immunised). If you do come into contact with either virus, it's a good idea to let your GP know.
