"used ortho tri lo for over 3 years  to regulate my period and it has been a positive experience. i have been able to use for 3 consecutive months or have a period every month. side effects: breast tenderness, increase sex drive and bloating close to menstration. positive are i did not gain weight, light periods, cleared my acne and it did not make me emotional and it is forgiving if i forget to take the pill. i really like this pill!"
