I had unprotected sex on my period. I'm on BC but when I was on my period I didn't have my patch on. He pulled out also. I'm only 16 and it was the biggest mistake of my life. Please help..

Please help? What can we do? You are the one that chose to have unprotected sex... how can someone on the internet help you other than to tell you that you are too young and irresponsible to be having sex?

Are you worried that you could be pregnant? Well, sure... it's possible that you are. Maybe not. We can't tell you because there is no way to know. Pull out is not a form of birth control and is way too risky. You will now just have to wait it out and see if you miss your next due period... if you do, then you will need to wait a few weeks and test.
