TMI!!! I am 26/4 me and my husband had sex last night it was wonderful after doing only one position i got kind of boring, so I looked up some information about sex positions during pregnancy and I thought I should try. So I got on top of hubby, I did the reverse cowgirl and there was oral sex and lots of Passion. So after we were DONE we slept, but around 1:00am i was sleeping I was laying on my right side and i felt my stomach very hard on the left side and I was feeling some kind of paing/cramp it was very discofortable. I am a FTM. Is this normal??? Should I call my Dr.?
