It has been 17 days of being on this new pill. My partner and i have always been careful about using condoms but that didn't happen. I had unprotected sex and am not sure if i am at risk of pregnancy. The package says 7 days, while i am hearing 2 weeks, a month, 3 months. Just a little advice please. My partner and i have both been tested for std's so that is not a worry. I just need to know if i need another course of action such as plan b. Thank you
