After having a mishap with what we were using, my boyfriend and I decided to use back up. About 6 hours after the incident, I took Next Choice, the generic form of Plan B. About 16 hours later, I took the second pill. Three days later, I started spotting, which turned into what seemed like a normal period for me (2 weeks early!) Should I still expect my regular period in 2 weeks, or has my schedule been adjusted due to the pills?
