I'm 39 weeks today. Yesterday I walked 4 miles and everything was smooth for a few hours until i had menstrual like lower back pain and finally was able to sleep. An hour ago I had really loose bm and tried going back to sleep but for the past hour baby has been so active, he's pushing against my organs to go down so low, I'm getting so much sharp pain in my vagina and feel like he's gonna pop out.... it hurts so bad and he hasn't stopped moving... was this normal? Or should I go in?
