Pregnancy week 15
(Sparx Media)

How's the foetus during week 15?

Your baby is about the size of an apple, weighs about 70g and is about 10.1cm long from crown to rump. 

Her heart pumps about 24 litres of blood per day.
She may start sucking her thumb and gets frequent hiccups as the diaphragm goes into spasms. 
The skin is so transparent that the blood vessels are visible.

What's with my body: Bigger breasts and sex determination 

Your heart is pumping up to 20% more blood than usual.
Your uterus may begin to rise past your hipbones any time now. Your doctor will start to measure "fundal height" - the distance from the top of the uterus (fundus) to the pubic bone. 
Your breasts are becoming larger and heavier. Wear a good supportive bra to relieve strain on the ligaments and your back. 
Skin pigmentation, known as chloasma, is likely to increase. Stay out of the sun to reduce pigmentation marks, and become best friends with your sunscreen, even on overcast days. 
Discuss with your partner whether you want to know the sex of the baby. Some people like to know so they can prepare for a son or daughter, others prefer the drama of "It's a girl!"
