Pelvic pain during intercourse?

Definitely go to the walk in clinic. This is something that needs to be closely watched and evaluated, especially if it happens more than once. There shouldn't be any pain involved in sexual intercourse and your bf should be more gentle with you if he knows it causes you pain. I would definitely hold off from having any sex until you know what's going on with your body. It could be an ovarian problem but getting it figured out should be the most important thing here for you. Good luck.
