A member asked:

How long does it take a new birth control to regulate your cycle after switching from another pill??

A doctor has provided 1 answer

BCP ?'s: If your cycle was regular on your previous oral bcp, a "new" brand or type will work immediately. If your cycle had "breakthrough bleeding", make sure to take the active pill within the same hour that you took one the previous day. When starting a "new" type of bcp's, take the first active pill five days after stopping the last active pill of your old prescription.
