Pelvic Pain after getting off the pill

So we are trying for baby #2 and I did not start a new pack of pills once my period ended a couple weeks ago. I first started experiencing some mild cramping a few days after not taking the pill and I assumed that was my body adjusting. Over the weeks it has gotten more noticeable and frequent (not painful). A couple days ago my husband and I had sex. I was good at first and then we switched positions (he was pretty deep 🤭) and I felt a jolt and had shooting pains with the thrusts. It only happened about 3 times and went away (we haven’t had sex since). But since then I almost feel sore inside. When I move/sit certain ways I get a jolt like I did during sex but not as intense. Im wondering if he was just a little too rough in that position or if the pain is associated with PCOS or endo? Obviously if this continues I’m going to talk to my GYN, just wanted to know if anyone else has experienced this. Sorry if this whole explanation was a hot mess 😫
