Heragest- TTC

Hi mga Mamsh. For those trying to conceive and irreg na menstrual cycle na mga mamsh na niresetahan ng heragest, is it normal na 2 days lang yung menstrual period? Usually kasi 4 to 5 days period ko and medyo malakas pero after taking heragest naging 2 days na lang sya tapos medyo kumonti sya compared sa normal period ko. Sino po may same experience? Salamat
