I am a ftm and 38+2 weeks pregnant.

Last night I was eating supper and suddenly a sharp pain hit me. So bad I couldnt move from where I was. I was trying so hard to keep calm. I finally got up and walked and almost collapsed from the pain. It lasted for about 5 minutes.. just throbbing. Afterwards it was just small throbs for a couple hours. It was smaller at night too. Baby is still moving and it hasnt come back as intense but could it be the start of labor or a sign its close? I was overwhelmed by the pain I felt. Ive had braxton hicks and lots of stomach tightening the last week or so. Baby has been as deep in my pelvis as possible since 33 weeks so she couldn't have dropped. Sorry for this being so long I was just concerned !!
