I am 38 weeks and 5 days (ftm) and I think I'm having contractions but I can't tell. I can't really time them because it's hard to determine when they start and when they stop. But here's the catch, only the top half of my belly gets hard. Just the top half. That's the other tricky thing. I can't tell when they start and stop so I don't know what to do. Please help.
