I started yaz june 22nd and it is now July 6th, recently I just started having HORRIBLE cramps about 4 days ago, they were so bad I even called into the emergency room. The nurse told me to take motrin, and I've been taking it as much as I can becuase the pains so bad. Then I realized what a great nurse to tell me to be on motrin when it increases the level of potassium in your body. So now I don't take motrin, or anything because I have been taking it on a regular basis now otherwise I would be laying in bed. I do not recommend this drug to anyone! Right now it's ruining my life these past few days. I also have had mood changes and increased appetite. My breasts are swollen and and are so tender. just know the facts before you start this pill, and make sure your serious about this drug.
