Hi, I have a normal period cycle of 28 days. Last month, my periods were due on 27 Feb but I had to postpone it for a few days, So, my doctor prescribed me Meprate 10 mg twice a day to be started from 24th Feb. I took the same and on 1st March at night, saw a brown spot. So, I stopped taking the medicine further and had my periods for normal duration. Now my periods were due on Mar 31st but they are 7 days late. Is it normal? Also, How much maximum time should I wait ? I am really tensed as my cycle has never been late before.
