So I'm on the pill and last week I noticed I was taking the pill on the wrong days because I think I missed a pill. My pack only came with one sticker sheet with my starting date as one single strip. But, I had 3 packs of pills and I couldn't take the sheet off the old pack. So I just told myself what days they were everytime I took it. Somehow I messed up and took Saturdays pill when it was Sunday. Then I realized I had missed a pill throughout the week. I then disregarded Sunday's pill and took Monday's pill on Monday. I know stupid, but I'm supposed to get my period either tomorrow or the next day if it comes. So my question is how likely is it that I could get pregnant? And no I didn't use a backup method.
