third trimester sex

#29weeks today, had some ✨relations✨ with my hubby earlier, and ever since then my sacrum/low low back/ between my pelvic bones on my back have been hurting sooo bad. we’ve been trying to find a position that works for us and today was the first time in awhile doing regular side lying situation so I wasn’t even doing anything crazy 🥲 has this happened to anyone else? am I not going to be able to have normal sex again until Im cleared post partem!?!
