I found out why I was feeling all this. She dropped
I've heard that diarrhea and cramping can be signs your going into labor! I'd get it checked out just to be safe :) good luck!
The same thing happened to me at 38 weeks. I went to the ER and had my daughter hours later.
If I were you I would get checked. I felt the same when I was 35 weeks and dealt with the pain for 2 days until it got so bad I gave up and went to the hospital and I was already 10cm dilated. The doctor told me if I would've token any longer I would've given birth at home. Honestly it's better safe to check.
