I was on Yasmin for 6 months before my wedding. i had to go to the hospital for the headaches I was getting....they were indescribably painful. i stopped Yasmin end of aug and got my period normal for sept-jan. then feb and march skipped but had weird cramping and nausea and then got in randomly in april but was brown blood only. then may skipped. i demanded blood work and got tested last tues for thyroid, glucose, insulin, and hormone levels to help rule out PCOS. i am worried i have pcos or premenopause from the pill. i should get the results tomorrow.
