If my menstral cycle starts on a Saturday and I have it for four days until a Tuesday or wednesay, when would be the best time to start an oral contraceptive the Sunday the day after my first day or the following Sunday when it has already ended?

Didn't the doctor the prescribed the birth control tell you when to start it? I hope you didn't buy these off the internet? 99.9% of the prescription drugs sold online without the legally required prescription are fakes, a best without the active ingredients of the real thing... and at worst... have dangerous ingredients. And that was determined from independent testing...

My doctor did prescribe them to me but I forgot the perscription in the office and just picked it up recently from last August she had to rewrite another one and then I picked it up.. forgot instructions.. I have taken it before but my period had ended on a Saturday and I started it the Sunday next day.. I was not aware that there is that high of stupidity in people to buy birth control offline..

Not just Birth control... any other medication as well. Usually people taking huge risks to save a buck.

Usually you start the first Sunday after your period. You can also ask the pharmacist at your local drug store as well.
