had sex, no period! D:

i recently turned 15 and had sex for the second time in my life on september 14th. I know some of you will say i'm too young and so on and yes, i know that. It was HIS first time and he wanted to know what it's like without a condom so we did it like that for a while. He did precum and i read somewhere that that can get u pregnant??? D: Then we put on the condom but he blew inside me (WITH the condom on)... but i got really scared still.

I was so scared and paranoid that I bought the day after pill and took it after reading the instructions and everything. My period was supposed to happen around 3/4 days ago and it's pretty normal these days. I'm totally FREAKING OUT becuase I haven't got it yet. I'm an emtional wreck and I would really like for some advice and whether to know what's going on yet. Will it be ok? :S

Any help will be appreciated, i'm desperate.

Thank you
