hi this a piece of info i extracted from a piece about two periods a month. ok the info come from ivillage another reasons for twice-a-month periods is abnormal thickening of the uterine lining. this thickening can be due to hormonal imbalance or to taking estrogen without a progesterone medication as well; estrogen causes the uterine lining to proliferate and become thick and lush while progesterone thins out the lining; a balance between these two hormones is necessary to ensure regular moderate periods. so it may not be as easy as i write but if you get a hormone test done from this it would tell you which hormone is out of whack it then would be to get them back on track by adjusting them. in my mind it should work try seeing an obstetrician perhaps he/she will understand this and make it work they must have seen it before. do hope this helps you. good luck
my doctor put me on birth control because i have a hormonal imbalance. how can i get pregnant with a hormone imbalance? . i have stopped taking the birth control pills because i want to get pregnant. however i am having my period every two weeks now.
