I am supposed to get my period in 8 days, This is my first month off the pill and i've had sex since the first week I stopped taking the pill.

Since yesterday I am very dizzy, I have been bloated for like 3 days and I get this really weird feeling in my belly, like cramps but they are just way too light. I know its too soon to know. And maybe even to have symptoms, I know I ovulated, thats for sure, but do you think I could get a positive test in a week? :) By the way I stopped the pill a month ago.
