Di have sex near my bf and its not the first time but it is the first time that i bled after have sex. should

i be scared? It's really not something you should pilfer lightly..but you shouldn't be that alarmed. There could be many cause of spotting after sex.
1. It may be an STD such as clamydia or gonorrhea which are both bacterial infections.
2. Vaginitis which is swelling or the cervix
3. Yeast infections and so on.
I think you should carry it checked out by a doctor..they are all treatable the quicker you get hold of checked out.

Not necessarily. If it happen all the time, be in motion visit your doc.
