My Boyfriend And I Are Trying To Conceive, I Just

My boyfriend and I are trying to conceive, I just stopped taking my Birth Control about a week ago, My body must have gotten confused because I started my period yesterday, and it should not come until about 2 weeks from now, If I didn't start my period these next few days would be my fertile days, but since I started does my fertility completely start over? And since we have been trying, is there still a chance I might be pregnant?
