What are some reasons why my period is coming a few days early? (i'm on the pill, haven't missed any pills and take it same time every day)
i've been on the pill for 9 months now and haven't missed a pill. take it at the same time every morning with exception to one day on the second week i took it 30 minutes late. my friend said that shouldn't effect it though. this is the second month it's been a few days early.
