I’m 17 and I had sex with my best friend, he had never done it before and all that so we did it! And the second time we had sex he was wearing a condom but he didn’t pull out to finish and did it in the condom, but the condom came of inside me and we got it out straight away but I’m now terrified I could be pregnant because me period is late only by a couple of day but I’m still terrified and idk what to do
