"the part i don&#039;t like about this pill was the first few months i started taking it when i switched from yaz, it made me gain 10 lbs and it took almost 8 months for my body to adjust to it. the positive part is, i have a very light period (when i have one) and i don&#039;t break out like i used to. now that my body is starting to get used to it, i am losing some of the weight i gained with the initial use of loestrin. it is a smaller dose of hormones from what i was taking- which helped reduce my migraine count to once a week versus everday."
