For the last 6-8 months for some reason the week before my period (and the week of sometimes) sex is SO painful. There are only a few positions that are mildly comfortable for me and (tmi but) the deeper my bf goes inside of me the more painful it is. It’s like a sharp stabbing pain that I feel inside of me but it only happens before my period and then it slowly goes away. I thought it was a one off the first time but now I’m thinking it might be endometriosis…? Does anyone know if it sounds like i’m on the right trail? If it is endometriosis, what should I do? If not, what could it be?
