I started taking the pill again about a week and a half ago and the past few days I've had light bleeding randomly through the day (sometimes it will just be a few spots when I wipe and other times it's like I'm about to come on my period). I know this is normal but how long can I expect it to last for? I never had random bleeding with this pill any other time I've taken it. I started my last period 2weeks ago so I'm assuming this isn't it.
