With all the commercials you see on TV about YAZ and Yasmin and all the problems it has caused, i cant imagine that the positives out weigh the negatives. Currently I am on
Levlen birth control, it has the minimum amount of estrogen
and it works wonderful! But because everyone is different, i would suggest doing some research on birth control types and find whats best for her, then talk to a doctor about those types you have looked over.
Good Luck!
