Mini pill

I’m in the mini pill have been for over a year now and I haven’t had a period since November... 3 weeks ago I had unprotected sex (with a guy I used to date) but now I’m getting mild cramping that comes and goes through out the day slight pain in the Side if my boobs but not overall sore and not even generally tender

Idk if it’s the pill that’s giving me cramps or what and just want someone’s opinion

I’ve had cramps like this before last summer and the doctor said it might be ny period coming and it did end up coming but he did a pelvic exam to see if it was PID but I didn’t feel any pain. I have on and off yeast infections and Bv which ivehad on and off for a few years but it goes on it’s on and just want to see people’s opinions on what it could be ?
