I am 18 years old and I had protected sex Jan 15th. I had my period on the 6th and I think I was ovulating. The condom broke and possible precum. Like 4 or 5 days later I went to my school nurse and I took a plan b and got Birthcontol the same day. My stomach had been really hard and when I press down on it, it's a unconforable feeling. I also pee a lot more. I am so scared that I'm pregnant. I'm going to take a pregnancy test on Feb.13 but i feel that I'm prenant. I don't have any other symptoms of pregnancy though. Just pain when I press down on my stomach and peeing a lot more. Did the plan b I took fail? Possible pregnancy? Or something else? I'm clearly not ready for a child. I'm plaiting on to stop having sex. Yes I JUST started birthcontrol.
