Birth control-depo

I've been on depo for about 2 years, I've never been pregnant but my boyfriend and wanted to have a baby so I stopped getting the shot back in march.. I never got a period on it and have my first regular feeling/looking period this month! We have sex almost everyday so we had sex the 5 days leading up to my period than actually when my period wasn't heavy, on my period. I'm in my fertile window now.. Is there a possibility that I could get pregnant?
