Yaz and zombie

I haven't taken BCP's in about 15 years. I recently started due to severe endomistriosis and extreme moodiness (which I believed was PMDD) I went to my gyno and she put me on YAZ. I am on my 2nd month of YAZ. My first month was fine and I actually enjoyed not having my period for the first time in a million years and my moodiness seemed to be gone. I am now into my 2nd week of my 2nd month and I have to say it sort of sucks. Im on the fence about this product. It has decreased the severity of my PMS symptoms as far as the pain goes, but I still got all of my usual symptoms (only less painful) except for the extreme moodiness. And, even though I have been consistent about taking the pill I have had a very very light but steady period for the past 6 or so days (which is actually longer than my normal periods). The other bad things about this pill is I have had a complete drop in libido and very extreme fatigue, to the point where I feel like a walking zombie. I would have to say the only thing good about it is the fact that my severe moodiness (during PMS) was completely gone, and it lightened my PMS symptoms and flow. So, I haven't decided if this is working for me or not.
