Girls, can you tell me what week of pregnancy starts at 9 months and how long does it last? Because my doctor just told me that I'm 32 weeks pregnant. But by feeling, I already feel like 8 or 9 months...I'm always sleeping, my blood pressure is often low, it's awful. They also scheduled an ultrasound, but it's just a regular one, although I thought it was time for a third screening...
