So I never start my period on the exact time of starting the sugar pills. I always start 2 days later than my actual sugar pills start. So I had unprotected sex 2 days after the sugar pills started & then later that night started my period. Then when my new pack of pills was supposed to start, I forgot to take it so I took it a day late. I heard sperm can live in a girl for 5-7 days so I'm worried since I had unprotected sex when I wasn't even on my period & that I started my pack late, that I could be pregnant. Could I ?
