I was previously on birth control before although stopped for a few months and have just recently started it again. With that being said, I was on the pill for approximately 2 weeks when I forgot to take it for 2 days and immediately got my period on the second day of not taking the pill. I stopped taking the pill for the duration of my cycle. Once my cycle was over I started a new pack for about 7 days. Am I at risk of pregnancy from unprotected sex on the seventh day of that new pack of pills ?
