I am 16 I was in the middle of my cycle and and I had sex but the condom broke so he pulled out and then came. So I went to the store the next morning and bought plan b and took it 16 hours after. I have had a stomach ace and felt dizzy at times. I'm also getting a lot more white discharge. It has been 5 days since the incident. I am freaking out cause I am not suppose to get my period till two weeks from now. How likely is it that I could be pregnant?
