Pills...

Hey girls, I just started in the pill like 4 days ago for the first time, I'm just 16 and I'm using it to regulate my period. I forgot to ask my gynecologist if I have to take my pills on my period, too. The thing is that there are 28 pills an I don't know if I have to take the pills during those days?

By the way, my last period was on August 11 till 19.

Can anyone help me, please? :( thank you.
