6 days before period

Me and my boyfriend aren’t really trying for a baby but if it happens it happens. I also know the app may be wrong a few days. But the day after the app said I ovulated I had a lot of white discharge, if honestly felt like I peed myself when it came out. Then I had super bad side pain, could be totally irrelevant. I noticed I’ve been eating weird and a lot, now today waking up my boobs are so sore to the touch, I’m 6 days away from my period. He doesn’t nut in me but sometimes he does nut and go back in. We didn’t have intercourse on ovulation day, but the days before and some after. Anything you guys could add would help.
