I am 22 years old female. I am having period problem from last 3months. On July my period lasted only for 2days which is usually 6 days in normal days. Then I had heavy flow on August and now in Sept. I have no periods. I am already a week late. For your information I took abortion pills when I was 20years. I had normal flow after taking pills but the no. of days (length of period) decreased from 6 to 4-5 days. Why am I not having periods? Is it related to the pills I took before and if so what are the consequences? Would it effect my future fertility?
