Me and hubby were having sex and all of a Sudden my stomach started hurting really bad on one side like it was feeling like the baby pushed up against my uterus on one side we stoped for s min and it didn’t go away for a while but then it did so we continued has anyone else had this happen I’m to scared to ask my doctor about it if it’s normal it felt like my uterus was stretching because the baby was pushing so hard
