you should go get cheacked out just in case.
Call your doctor. It might just be because you tensed. With my son, I fell on my stomach/side and I was 39+5 weeks pregnant and they monitored me because I was worried and than sent me home and said I was fine. He was born at 40+1 and was healthy
They say not to go ice skating while pregnant, I hope everything is ok! Get checked out asap :)
Update: going to have it checked out Friday but now that I'm laying down getting ready for bed I'm feeling normal movement so I'm sure everything is fine
Probably shouldn't go ice skating though. =) glad everything is okay!
