This is why a lot of people only use it for the first half of their cycle (and I've read that you're technically supposed to wait to start taking it until your period is finished, but not everyone does this). I don't know if you're taking it every day of the month, but it's best not to. The body naturally drops in estrogen so that it can have a period; when you're taking hormones like PM, that will disrupt your body's natural cycle.
