Blood clots

Hey girls I have a question. Last week on Friday i got my period and on Tuesday i finished. Today i had protected sex 3 times in a row in the morning and i went to use the restroom and everything was fine. Until 30 minutes ago i went to the restroom and when i wiped i saw tiny blood clots and i got really scared I don't know what it could be. Maybe my boyfriend hurt me inside and that's why those things came out... Has any of you been through this?? Please help
