Going from Yaz to Yasmin

Hi everybody! I've been taking Yaz for a month now and it's taken a toll on my digestive system. I have IBS and most pills make it harder for me to digest things and bloat me.

However, I was on Yasmin last year (the stronger version of Yaz) and it didn't seem to give me digestive problems on the first month. It did give me rather persistent migraines, which I never have.

My question is: do you think the Yasmin headache will go away if I start taking it again for a longer period of time? Thank you! :))
