For the past month I've been taking diet pills heavily. Now my period is 10 days late. I don't think I've gained or lost weight. I feel normal, a little worried...

As for sex- didn't happen. There was a bit of dry humping involved, but as far as I'm aware no ejaculation and I was definitely wearing my underwear.

I don't see how I could be pregnant? I'm thinking it's the diet pills messing around with my hormones or something?
