It doesn't sound like your AF if you ovulated a week ago. If your cycle is short it is due to a short follicular phase. Your luteal Phase doesn't shorten like that.
I definitely without a doubt ovulated a week ago.

I don't hang out with many chicks, one is pregnant, the other hasn't had AF back yet from having a baby so it's not that unfortunately.

Maybe it's my hormone levels since I've been getting hot flushes lately and pimples...
