A broken hymen isn't necessarily a sign of impurity. They often break during exercise during childhood, gynecological exams, or use of tampons. Not every girl is born with a hymen, either.

Also, not every girl bleeds the first time they have sex and some bleed when it isn't their first time.

I would suggest going to a doctor that you trust to talk about this issue. I know you may be scared, even though you are a virgin, that you may not be believed by your future husband. Fortunately or unfortunately, not even a doctor can always tell if a girl has had sex or not.

My advice would be to only marry someone you love and trust enough and who loves and trusts you. That way, you can have an open and honest relationship. He should believe your a virgin because you say so, not because you bleed. (I know that's easy for me to say).

Remember that being a virgin isn't just a physical thing, it's emotional, too.

I wish you the best of luck in the future.
