People on here seem to be confusing Yaz and Yasmin--they are not the same. Yaz has less estrogen than Yasmin and Yaz has 24 active days vs Yasmin that has 21. I've been on continuous Yasmin pills (no breaks) for 8 years or so and it's been a godsend. It stopped my hormonal migraines and gives me the right amount of estrogen. In fact, I work with a specialist and take two Yasmin bcps a day to get what my body needs to manage the perimenopause I developed in my 30s as well as my migraines.
Birth control pills effect everyone differently and that's why it can be a long haul to find the right one--especially if you are prone to hormonally induced migraines--and I have them worse than ever even when I'm not having a period or ovulating. It can also take several months to determine if a birth control pill will work for you and often that means putting up with side effects that are short term--possibly bloating, emotions, etc (certainly not life threatening side effects like hives). When you start a bcp, there is often a very uncomfortable period of time--could be the first two months as your body attempts to adjust to the changes. It's a matter of being your own advocate and tracking the side effects--or what might be your body adjusting--and seeing how it resolves. As I mentioned at the beginning, everyone is different. I've seen that with friends who try to use Yasmin--some it works, others, it's a nightmare.
And for those wondering about weight gain--Yasmin has qualities in the hormones that are diuretic in nature, so typically someone will not have bloating and should drink more water...and get potassium checked at least yearly.
I love Yasmin and for me, it saved my life in terms of quality of life managing my migraines!
