Unprotected sex

Aimen

Me and my partner had sex unprotected

He didn't ejaculated inside me

But he had some ejaculate from the last time he came so I guess there must be some there on the tip

Im just over analyzing but tomorrow is my fertile periods first day

I'm going to take emergency contraception pill right now

Should I be worried about a pregnancy?

Also if I vomit after taking the morning after pill what should I do after that?
