I took meprate 10mg on 20th day which was 22nd of Nov to 26th 5 tab for 5 days.. My question s when should I consider my period date as I still did not get my menstrual cycle.. Is it third of Nov or 12th.. As I have crossed 3rd Dec.. Do I need to wait till Dec 12th. My age s 30th.. Usually I get my cycle after 5 or 6 days using meprate.. Pls answer me.
Thank you..
