Hi Anon,

If you usually experience irregular cycles, it might be due to that.  But some women also experience changes in their next period.

Well I was irregular before goin on the pill..I would only get it about 5times a year but once I got on the pill I would get my period regularly. Could it be the fact that im irregular?

Hi lavender,

Welcome to EmpowHER.  Are you due for your period.  Some women experience changes in their next cycle after taking Plan B.  If you wait a few days. If you still don't' get your period, it might be good to see a doctor.
