heyy i have quick question

according to my cycles (i usually know when im ovulating and when im about to start, i keep track and know my body well) - i should be ovulating right now. I had pretty bad cramps because of it yesterday.. however, i'm just wondering if it's possible to be pregnant, and still cramping during when I'm supposed to ovulate, or if I'm actually ovulating AND pregnant or just cramping and pregnant.. otherwise, i just assume i'm only ovulating..
I didn't THINK i was pregnant, but then this question occured to me.. my bf and i were going to have sex and got erm...halfway "there" and realized we didnt have any condoms, and I just read some posts about "pre-cum" and how sometimes it has sperm in it.

I suppose I could get a preg.test - but I figured if I'm cramping from ovulating and that means I'm not pregnant, that would save me the trouble!
Thanks!!
