Pregnant or not?

Wednesday my boyfriend and I had sex with a condom but it ended up breaking and he came, but did not come inside me. I've been having cramps and constipation. That of which I went to the doctor over, they said I was very constipated and put me on laxatives, I also found out I had strep. today was my first round of medicine and about an hour ago I had very bloody stool, is there any chance I could even be pregnant or is it just my worries? My period is two weeks away and it's nerve racking
