Help please

So on the 17th of this month I had sex and the condom fell off and I thought I saw it fall on the bed well it was over 12 hours later that I realized it was in me and my mind went to infection so I ended up going to the doctor about 40+ hours later and getting the morning after pill and check out ... Can some of you tell me your experience with the morning after pill ... I'm late on my period they said it can be up to a week late .. but I have no period symptoms I mean mild cramps here and there but not my usual symptoms and I'm just a little worried ... Anyone get pregnant after taking it ? Can you tell me some of your experiences as well?

I know it's not a birth control it was my first time ever taking it and just want to know if what's going on with my body normal

I haven't had any implantation bleeding but I didn't with my daughter either.
