I am 26 years old proud mother of 3 amazing kids. I was diagnosed with Pcos. I had first baby 2009 doctors said gall stones caused bad pain. Had gallbladder removed. Had my second child 2012 had pains again went doctors said had small cysts. Then in 2014 had my last child alto of issues again. Was then doctor confirmed PCOS as cysts were worse. I got fixed after that baby and my periods have been out of wack since. Seem like start get better now worse. When haven my period I am drowsy, weak, nauseas, cranky, no appetite and in alot of pain to point where I cry.
