I am a 17 year old boy, and 2 days ago had sex with a girl. I put a condom on before i went inside her, but i must not have put it on properly. A while after we had been 'doing it', i noticed that the condom had slipped off. I do not know how long it had been off for. Immediately i found the condom and put it back on. I then came inside her about 1-2 minutes after i had put it back on. I am so so worried that she could be pregnant. I have heard about how pre-ejaculate contains sperm, and i am worried that i could have had some pre-ejaculat and that some could have gone inside her durng the time period that the condom came off.

I have voiced my concerns to her however she does not seem to be very worried. She told me that she had 'had her period' 5 days before we had sex so there was very little chance that she could be pregnant.

However i remain very worried. I cannot sleep, i cannot concentrate in school, i cannot really function properly at all. I dont think i could live with myself if she became pregnant. I have tried to convince her to take an ECP (morning after pill), however like i said earlier, she does not seem very concerned, and told me that there was no need for her to take it as when i ejaculated the condom was on, and she had had her period on tuesday - we had sex on the saturday after that.

Could some one just please talk to me about this as i am seriously freaking out and close to tears as I write this. Does anyone have any advice or something.

Thanks for your time
