Does Switching From Yasmin To Requip Cause Spotting Between Periods?

new prescription: requip
old prescription: yasmin
I have miss a couple bc pills in the last 2 years and never had menstrual spotting between periods before, now that I have started taking requip my whole life balance is out of wack. I stay up late, i throw up my dinner ever other night if i am even hungry enough to eat, etc. i missed a bc pill the other day and now have a heavier spotting and i am wondering if this has to do with the new prescription of if there is another explanation
