Hi..my LMP was on march 11, 2018, i took clomid for 5 days on my 2nd day of period & hormone test are within normal limits. During my ovulation my doctor prescribed me Duphaston for 10 days. After 4days of stopping Duphaston, i had mild bleeding for 3 days, 1 week before my expected period, is it possible that this is implantation bleeding? I did qualitative bchg after 3 days of bleeding but the result is negative.
