Please comment below: If you have irregular periods, how irregular are you? If you're on BC, what were they like before BC? Anybody have experience with irregular periods going off of BC? That's what I'm dealing with right now. Spent years on BC, been off for about half a year. Periods were relatively regular the first few months but now they're getting further and further apart. I was never very regular before BC, so I don't know what to think.
