I have irregular cycle. was on yaz (drospirenone and ethinyl estradiol) pill in jan stopped after 3 wks & taken plan b 3 times since then. should i expect period to be super irregular?

Possibly: If you have a history of irregular periods sometimes going on birth control will regulate periods when you stop but other times you revert back to how you were before you were on the birth control. If you are interested in birth control and regulating your period I would speak with a doctor about you options.

This could cause: irregularity. Potential side effects w emergency contraception includes menstrual flow changes (spotting, bleeding, early or late period). If you have needed to take plan B 3 times in 3 weeks - it is very important that you use some form of reliable protection consistently.
