About To Start Marvelon. When To Start The Pills?

I am about to start taking Marvelon - Birth control . I was told I could start the Sunday following the end of my period, which would be this Sunday (June 10th) I would like to confirm that, also another thing I would like to confirm, is how long after starting this contraceptive is it safe to have unprotected sex. I know that it s never really safe but me and my boyfriend are very serious and have both been to our family doctors for tesst and we are both a-okay.

Hi, Oral Contraceptive Pills like Marvelon act by raising the levels of female hormones in the blood thus preventing ovulation. They are most efficient when started within the first five days of beginning of the cycle, when the natural hormonal cycle of the body restarts. After the first five days, it takes about 7 days for the hormones to reach effective levels for contraception. So if the pills are started within first five days of the cycle, first day being the first day of menstruation, you can have unprotected sex without fear of pregnancy. However if started after the fifth day you need to use another add on method of contraception like condoms during the intake of the first seven active pills. Also for the pills to be fully effective you need to take the active pills regularly at the same time without a break as prescribed.
