So I'll be 39 weeks on Tuesday but gained 7 pounds this week. Between Thursday till today I gained 4 pound. Today I have been having issues peeing and it don't hurt when I pee but only peeing small amounts but drinking alot. My legs and face blew up. Any ideas of what's going on I'm having a hard time peeing. I also keep getting these sharp pains on inner thigh ever time I move where I can't move my leg and it kills me.
