It’s been a week since I ended my period and my discharge is normal. When I have sex with my boyfriend the day after or maybe a couple hours later my discharge is dark brown or even sometimes it’s blood as if I’m on my period and it’ll stay like that for a day or two until it goes away on its own. Idk if it’s because of sex or just my body, maybe I’m thinking it’s sex bc that’s the only logical reason I can think of. I don’t understand why this happens? Please help me I’m worried.
