Can birth control pill be used to get periods ?

Shruthi

Hi everyone!

I had my last period on July 18th and on 2 August I had taken emergency contraceptive ellaone. I still haven’t got my period and it’s already 15 days due now. I did pregnancy test twice and it’s negative. Can I take 21 days birth control pill for just 5 days from now to get my period.

Please someone assist
