Why start birth control on Sunday?

Answer 1

Pills are generally set up by weeks in the pack. Starting on Sunday just makes things easy to keep track of to reduce errors.

***Also... the major reason is that starting them on Sunday saves you from getting your period over the weekend. You should get it on a wed-thursday (that's how yaz works for me).

Traditionally, women in the US started the Birth Control pill on Sunday. This has an obvious disadvantage - your health care provider's office is closed on Sunday, and many women start their pill late when they notice too late that they're out of pills. Do yourself a favor and consider starting on a weekday, as they do in most other countries.
