You are now
You are now
Your baby is now about 16 cms long - the length of a pen - and weighs around 135 grams. Your baby's teeth have formed in the gums and the first tiny buds for the permanent teeth are forming now too. Your baby's placenta is doing an amazing job, giving your baby all the nourishment it needs. It protects your baby too - preventing most infections crossing over from your bloodstream. It also acts as an effective barrier to many harmful substances, filtering them out, so they can't affect your baby.

Boy or girl? If you want to know the sex of your baby you can ask at your scan, but some units have a policy of not telling. If this is the case, at least you'll have a surprise nobody can spoil!
Friends and family will no doubt try to predict the sex of your baby. But researchers have found that guesses based on so-called old wives' tales - keys, rings and the shape of your bump - were no more reliable than chance. But it's still fun guessing though! Something that isn't much fun is thrush. It's common in pregnancy. You might need a seven-day course of treatment, rather than the short courses more usually prescribed. See your doctor if you think you have it.
Pregnancy tips: now that your bump is growing, be prepared for your friends and family (and even people you don't know) to want to touch it. Some mums-to-be don't mind all the attention - others find it hard to handle. If you're not a tactile person, and would rather your bump wasn't touched, just politely say so, or you could tactfully move away!
