When you're 31 weeks pregnant, your baby is pretty active, and while somersaults and jabs to the ribs can be somewhat uncomfortable at times, they're also signs that all is well.
When you're 32 weeks pregnant, your baby is almost fully developed and is working on fine-tuning the skills she'll need once she's born, namely, swallowing, breathing and sucking.
At week 37, health care providers consider a pregnancy to be full term, meaning that you could give birth now with a relatively low risk of complications for your baby.
