Proper education on Menstrual cycle

Most women lack proper education about their menstrual cycle. This leads to them taking postinor-2 like groundnuts. A woman with a regular menstrual cycle is fertile 6 days a month; that is 5 days before ovulation and on the ovulation date. Therefore, there is no need of taking contraceptives and emergency pills every weekend.

I read an article where women who had taken contraceptives for extended periods struggle to conceive when they are ready and sometimes they don't get their periods while on these contraceptives. This is wrong.
