First time on the BC Pill

So I was prescribed Sprintec over Nurx.

Has anyone tried Nurx? Opinions?

I live with my very strict parents and figured to do it this way to make is discreet without having to go to the doctor.

I know my health status, just wondering how the company is!

When my Rx gets here I’ll be just finishing my period. I started bleeding on Saturday and expect my birth control around Sunday.

Should I take The Pill right away?

How long until I’m protected and can have sex and use The Pill with no other method?
