Starting birth control andmissing a period

Patient: I started using birth control almost two months ago. My period came regularly the first month, starting the first day of the sugar pills. I had sex on the 4th of this month. We used a condom and I don’t think it bore. I am now on the second month sugar pills, but I have not started my period (first sugar pill on Monday)) I missed a couple pills this month. The first one I took later that night and the second time I didn’t take it until the next day. Is it possible for me to be pregnant?
