Thanks for using healthcare magic.
I have gone through your available history.
If you have sex for the first time, bleeding is common due to hymen
If it is not for the first time , then it needs to be thoroughly investigated. You should consult gynecologist for expert examination and evaluation. Doctor may rule out vaginal tear or cervical pathology if any.
If you have taken contraceptive
pill regularly, than there is no chances of having pregnancy
but if you have missed dose in between, there may be a chance of getting pregnant.
I hope It will help you.
