No: No. Need to do an entire cycle (usually) to start a period. Sometimes, depending on where you are in your menstrual cycle, doing a course of just progesteron for 5-10 days then stopping it can cause you to menstruate (have a period)

A 38-year-old member asked:

Hi docs, would birth control change my period cycle?

Possibly.: Most women will have lighter, less painful and more predictable periods. If you are not currently having a 28 day cycle you usually will when taking a birth control pill. If the pill changes you cycle it will normally be a helpful or desired change.

Yes.: You can start ocps the day you get your prescription filled. They will not work for the first month, though.

That response is actually not accurate. You can start your pill any time during your cycle ( this is called quick start) and it will be effective one week after starting. You should use back up (like a condom) for one week, if you start your pill any time after the first week of your cycle. one month is unnecessary. Remember the first day that you get your period is the first day of your cycle.
