Tmi question.... 😳

Ok, so I have read on here that some girls use preseed and then the next day they have a brown, like dry blood discharge. Is that bad?? What happened if it happened to you? I have been ovulation this week and been having minor cramping.. Used preseed last night, which was amazing but then today had a little discharge.. Not a lot though.. Any comments or advice is wanted.. Thank you ahead of time..
