I am wondering if its the ingredients in the yasmin that could be doing it besides the
progestin and estrogen? Where you taking it continuously with the yasmin 21 or the 28 day?
MARVELON21 contains the below ingredients
Each white, round tablet contains desogestrel 0.15 mg and ethinyl estradiol 0.03 mg. Nonmedicinal ingredients: colloidal silicon dioxide, hydroxypropyl methylcellulose, lactose, polyethylene glycol, povidone, starch, stearic acid, talc, titanium dioxide and vitamin E.
