No problem, I was just not too sure what you were saying, I read it a few times and took away different things!
Yes, you should have less side effects, because it is a lower dose. You should still wait 3 months to decide as that is how long it takes for your body to adjust.
I think it may shorten your period, I never had mine when I was on yasmin. But everyone's body reacts differently. I know they put women on birth control to make the periods less heavy and shorter. So in theory it should!
Hope I helped.
