Your 9 months Pregnancy You're 15 weeks pregnant You’re in the 15th week of your pregnancy, here’s what your baby will be up to… 1 of Ad break How big is your baby?Your baby is now around 10cm long and about the size of a baby sweetcorn.Now find out how your baby is growing… How is your baby growing?While your baby's limbs are now fully formed, they look very thin and fragile, as she has yet to put on her pre-birth fat stores. She can bend her fingers into fists although this is something she’s not yet able to control. Her legs are growing longer than her arms and her bones are becoming harder. As your baby moves around she practises breathing and swallowing. She inhales and exhales amniotic fluid, helping her lungs to develop and swallows more fluid, passing it out through the bladder. Downy extra-fine hair, called lanugo, is starting to appear on her skin. This will help her to regulate her body temperature. Amazingly, this hair grows in patterns across her body, which looks a bit like fingerprints all over her. An ultrasound test now could probably reveal the sex of your baby, but most parents-to-be who want to know whether they're expecting a boy or a girl don't find out until their 20 week scan. Now find out what’s happening to your body… What’s happening to your body?Well, well, well – guess what, your libido may be returning and for some of you, this could be a chance to have some of the best sex ever, as some mums-to-be find their experiences are heightened during pregnancy. Not so good is that pregnancy can increase the likelihood of you getting thrush. The hormonal changes going in on your body encourage can create the right conditions in your vagina for a yeast infection, such as thrush, to flourish. Symptoms include a white discharge and itchiness or a burning sensation. Although thrush isn’t dangerous and won’t affect your pregnancy, if you don’t treat it, your baby may contract oral thrush while passing through the birth canal. Thrush can be easily and safely treated while you’re pregnant – talk to your midwife about treatment.
