Cerazette spotting?!

Manda

Hi!

So I've been on cerazette (mini pill) for just under a month and last week I slept with my fwb without a condom.

My next period is due on the 30th roughly (I have pcos) but since Saturday evening I've had very, very light bleeding? It's much lighter than my regular periods and a week early, is this normal or should I be more worried?

Thank ya!
