I started taking Yasmin about 1 month ago and seem to be experiencing the same side effects as many of you all. I know that many birth control pills can have side effects but Yasmin has been particularly bad for me. I have been getting dull headaches pretty frequently that just seem to linger for long periods of time. I have been experiencing nausea as well that I couldn't seem to figure out. The worst side effect, however, has been the MOOD SWINGS. My poor, loving (patient!) boyfriend! He's the one that has to take the worst of it. I find myself picking fights for no reason and getting really upset over nothing at all. I will go from happy to tears in split seconds. I know these emotions and sudden mood changes are not typical of my behavior yet I can't seem to control it. I feel like I have split personalities sometimes. I am getting off this pill as soon as possible and I suggest anyone with these same problems do the same! I can't wait to feel like myself again and feel in balance. I want to be happy like the person I was before I starting taking Yasmin.
