Would this change have any affect on my current cycle? I am on week 4 (the white pills) of Yasmin. This is my first time on it, prior to this I was on Aleese. I started Yasmin on the Sunday that would have been the start of a new pack of Alesse, but being that I am on the white pills now, I figured I should be starting my period but I havent yet. I guess ultimately my question is that if changing bc pills would affect or slow my cycle in any way?


Thanks for any help you can offer!
