I just had a baby five months ago. Started taking Yaz at my six week check-up. I am 28 yrs old. My side effects include: mood swings, MAJOR LOSS OF SEX DRIVE, weight gain, headaches, nausea at night before bed, Inability to pay attention, Restlessness, backaches, An aversion to touch, sometimes I feel as if I don't have any emotions at all. depressed for no reason. and so vary tired all time. I had taken Yaz before and experienced some side effects but was only on for a month my effects were headaches, and break through bleeding. Had a baby and tried it again and now I am just wondering what is wrong with me. My wonderful husband has been so understanding and wants his wife back lol. After reading other postings I am not going to finish this months pack and stop this craziness once and for all.
