"pros: i never became pregnant, i had less frequent and severe cramps and it may have helped with acne although i  started a new regimen around the same time. cons: within the first month of starting i had a yeast infection and over the next 2 years i would have some kind of vaginal or bladder infection every other month. my libido decreased dramatically and in addition to that i was constantly dry down there. i experienced some dizziness and nausea which is to be expected. lastly, i became a huge cry baby when i used to be able to count how many times i cried in a year on one hand."
