Hi, i stopped taking pills( Yasmin) last March 22,( i was not able to finish the pack) , LMP March 26 that lasted for 4 days, still have no period , went to the OB, and prescribed Duphaston 2xa day for 5 days. My last tablet was last Saturday, and i have been experiencing abdomen pain, sore breasts. Took a PT test before taking Duphaston and it shows negative results. Still have no period for about a week now, my Ob says, its should come 3 day after the last duphaston.I was trying to conceive a baby.
