was it your first time having sex because I hear that sometimes people bleed after they first have sex or it could just be spotting which could mean that you are going to have your period soon but spotting can also be caused by stress
I think the biggest problem is that it sounds like your boyfriend just inserted his penis into you without asking. Not the greatest boyfriend. Plus you are no longer a virgin even if your hymen is still intact as he entered you.
Well it suggests that your hymen might be broken indicating that you are no longer a virgin.
