Hi Mia, I am 28yrs old and I face trouble with irregular periods.My GP advised me to take Ginet -84. I took the tablet for 21 days( yellow tabs) and continued to take the white tablets for 2 days now, still i havent got my peirods. I am a bit worried now. Although this contraceptive was not given as birth control pill for me, my doctor advised me that it can make my menstrual cycle normal and back to routine. Kindly advise,
