The Pill... Help?

Im on the pill and my boyfriend cums in me when we have sex (not that often). One time I forgot to take my pill but that was over a month ago and ive had my period since then. Recently, I've only been late by 40 minutes. But on the last day of my last pill pack, I dropped the pill by mistake so I decided to make the the first day of my sugar pills. Did that increase my chances of getting pregnant?? I got my period normal that month but i'm on my third day of sugar pills for this month and I haven't gotten my period. I take them perfectly every other day!
