Helppppp

So about two/three weeks ago, I had a quick fling. This was a person I've been talking to for a while but we just recently had sex for the first time.

This is not a person I plan on being with in the future. It was just the heat of the moment............... But he came in me. Completely accidental (he used a Condom but I'm guessing he took it off while we were having sex). We both were calm about it we just took the awkward ride to the pharmacy. We went to buy a Plan B, but they only had the generic brand (weird I know).

We settled for that being that that was the only Rite Aid for a couple of miles. I took it and that was that.

BUTTTTTTTTTTTTTTTTTTTTTT

My period was due 3 days after the sex. EC sometimes halts your period so u wasn't too worried when it didn't come 3 days later but it's been 3 weeks. I'm pretty sure it should have been here by now.

I'm just wondering what I should do. This never happened to me before.
