hi...i am a married woman,33 yrs,with a daughter who is 4 yrs old.But unfortunately i had a miscarriage in September in the third month of my second pregnancy.i underwent a D&C and after that i had my regular periods the next month on 21st October and then again on 21st November.Now I am going on a trip on 17th December to 22nd December and i wanted to delay my periods for a few days.Will I face any problem with regesterone tablets, like irregular periods or excessive bleeding?Or later if I try to conceive again.
