When you start your period do you stop taking the hormone pills and start taking birth control pills again?

It depends with the reason you were taking the hormone pills in the first place, if you were on them because you missed your periods and they were supposed to regulate them, its safe you only stick to those hormonal pills for the time being. Hormonal pills and Birth Control pills both contain synthetic versions of the female hormones estrogen and progesterone that work to change the way your natural body hormones work so that your body responds to normal functions; ovulation/ pregnancy. So since both of them are hormone changing pills, they have different functions which could mess up your body in a drastic and unhealthy way. So, see a doctor just to make sure if you can, just Incase the kinds of pills you are taking are not high in estrogen.
