Ma'am /sir I am 22 years old. I had intercourse with my boyfriend on 23rd Jan I took unwanted 72 within 2 hrs I had my last periods on 15 Jan and after pill heavy bleeding occurred on 30than till 2~3 days after that till now my periods didn't come. I checked for pregnancy using prega news on 17&25 Feb & 5 March all the time test was negative & even no signs of pregnancy but I felt weak so I started taking good diet and exercises for periods (from past 10 days) to come but no result. Earlier my periods used to be on time with a cycle of 30 ~32 days. What should I do shall I still wait or take medicine for periods to come at least once. If to wait then how much to wait. I am very much worried and disturbed.
