Hello doctor. I m 20 , i started my periods on 3rd of this September on the expected date, it lasted normally for 8 days, after that it stopped for a day then continued again with very less blood and than after 3 days or more bleeding started to get more ,just like i normally have on my periods.. Basically its been almost 20 days that I m on my periods. I m not sexually active I ve been taking contraceptive pills Diane 35 , for 8 months which my dermatologist had recommended due to acne, it has never caused any problem On the 11th day of abnormal periods i stopped taking the medicone and I m not taking it since then
