Pregnancy Week 31: Physical Development
The feeling of breathlessness especially, might increase when you climb stairs or try to talk continuously. This is no cause for concern. It happens because your uterus is pushing against the lungs. You might feel that you are gasping for air but your baby is receiving enough oxygen. So don’t worry!
Your bra size is still changing and you might need to get a larger size yet again but remember to not use underwire bras while nursing.
This is also the time when you will notice your breasts leaking of colostrum. If so, try tucking some nursing pads into your bra to protect your clothes. There is nothing to worry if you don't experience this. Your body is preparing for nursing the baby and your breasts are making colostrum even if you don't see it.
