I usually have unprotected sex (not really unprotected as I’m on the mini pill) twice a week, last week my boyfriend said he was close to cumming inside of me. My breasts became sore a few days after, but I usually get sore breasts before my period. I’m only worried because I’m not due for my period for 2 weeks and my breasts aren’t usually sore this early. I’m just an anxious person. I have never missed or been late with my birth control pill, so chances may be low, but I just would like some reassurance.
