Hi Dr. Purushottam welcomes you to HCM virtual clinic! Thanks for consulting at my virtual clinic. I have carefully gone through your case, and I think I have understood your concern. I will try to address your medical concerns and would suggest you the best of the available treatment options. 1]Please do not panic or do not worry. 2] Many women experience post pill amenorrhoea, i.e. no menses after stopping the pills . It is rare but not uncommon. 3] The pill that you have taken is progesterone only pill - POP, it takes 3 to 4 weeks to restore lining of uterus- (endometrium)- to be thick enough to peel off and start menses. 4] If you have already passed 2 to 3 weeks after stopping pills, and urine test is negative; I will suggest to use barrier method like Condom; and a course of low dose pills like OVRAL L once at night for 21 days.After finishing this course, you are supposed to resume menses within a week s time. I hope my answer helps you. Thanks. Wish you great health.
