I'm 20 weeks and after dh and I had sex last time, a few hours later there was so much pressure in my vagina, most likely my cervix, and I could barely walk. Anyone else have this issue? Sex was too painful when I was pg the first time, like I was always a virgin, and this time it doesn't but now this symptom. Last time we didn't have sex most of my second and third trimester. (Poor dh)
