Hello, i have really really bad pms. And because of this, I m on birth control. Microgestin fe 1/20. I told my gyno how bad the pms is. And she recommended, for two months i just take the white pills, not the brown. Which will purposely stop my period for two months. It did great. Now on third month here. And i got period at beginning of the month. And now i got it again. So this October I ve had two periods.
