if you haven't had issues yet, I'd say go ahead and have your fun. but if you notice spotting the next day, make sure you don't do it again for a while, and if you keep spotting, go to hospital and get checked. me, I'm not allowed because I had threatened miscarriages quite a few times in the early stages of my pregnancy, so my ob said to refrain from sex. lol. I don't have sex anyways.... my baby's father broke up with me b4 I found out I was preggo...
i have and I'm still in my first trimester
