Pregnant?

So I was waiting a little TTC and was using condoms. But the other day SO and I just didn't have time to put one and after a couple hours I check and noticed that it was on my fertile window. 2-1 day before ovulation. I actually felt when I ovulated. Now I've been feeling, bloated, constipated, not a lot of appetite and a bit dizzy/tired.... I don't want to test yet, but I could be pregnant?
