Hi,i m taking duphaston for the past 6months. In the beginning i was nt taking it regular. But, for the past 3months i m taking it on a regular basis. once i started taking it regularly i got my periods on 29th, 28th day. This month i still didnt get my periods. today is my 34th day. i stopped the tablet on 25th day, started on 16th day. i m also taking metformin daily along with this tablet.I m little bit confused if it is a missing period or a sign of pregnency. Please let me know what would be a better option to know the actual reason.I think Home pregnancy test doesnt show the accurate result always.
