actually, slight bleeding can be expected during the first few times that you have sex, so considering you've had only little breaks between each count of intercourse, it really isn't anything to worry about. The only time I'd worry is when the bleeding either wouldn't stop or got heavier. Otherwise, this is all within the normal range, and nothing to loose sleep over.
However, you should indeed head to the gyno as soon as possible. - For a Pap, an STD screen and discussing birth control, too. So make an appointment today, eh?
