I had sex with my boyfriend and it was using a condom, he then thought something was leaking down his balls and we panicked and stopped straight away, there was no signs of any holes in the condom I was stressed and worried (he even filled it up with water to make sure) I wasn't sure if it was my cum or his. I then got my period a week late from when I was due and it was really heavy and I'm still worried sick.. I can't get the whole thing out of my mind can someone help???? I'm really young 15 - 16 and I do not want to be pregnant.
