It’s day 13 since my last period and I’m having brown discharge I don’t normally do this, and my periods are always super late. I haven’t had sex sense I took a Plan B, it’s been about 3 weeks sense I took the plan b but I have symptoms where I feel like I need to pee more often (not a crazy amount) pelvic pain and again the brown discharge. I don’t know what Is going on with me?
