abnormal uterine bleeding
"I am currently on my second pack of Seasonique. I was previously on Yaz which worked great for me but I wanted only 4 periods a year.  I am trying to look past the side effects because having only 4 periods a year, you are willing to take a sacrifice.  I have experienced severe breast tenderness during the first few months also my acne has gotten a little worse.  I have been breaking out with a rash since I've started the medication, and have had mood swings in the beginning. I haven't spotted at all, the periods are fine and manageable, but I feel Yaz had more positive effects like clearing my acne and not making my hormones go out of control, but 12 periods compared to 4? I am still on Seasonique and willing to let my body get adjusted."
