Hello, can you tell me if at 38 weeks pregnant my belly is hard. I don't feel any pain, tightness or discomfort. Is it normal for it to be hard? I think the baby might need more space already, so maybe that's why my belly is hard. Also, my hands and feet swell very often, not just in the morning, but also when I sit on the toilet for longer than 15 minutes, walk around the yard for an hour and suddenly it happens, it increases by two times. Is this normal? Or not?
