Huge waves symptoms and conditions

I have been on yaz for about 5 or 6 months now and it was great at first since coming off low estrine, I was havening serious side effects, but starting yaz it was awesome for the first few months now i have huge waves of nausea, constipation, back ache, some headaches, EXTREME mood swings, and depression*, bloating, my breast are always sore, i have gone up a cup size, my boyfriend cant stand to be around me! i have no drive any more, im just tired and my stomach hurts all the time i still have bad cramps, even though i have no acene any more and i have light periods all these problems are making me feel worried that i am pregnant all the time even though i take bc like i should i still don't trust bc so we still wear condoms, so i no that im not. i thought i had everything wrong with me,i have gone to several doc. but they found nothing i have IBS also so suposably my stomach was hurting from that. i know when my IBS has kicked in and thoughts pains were not it. but all these post i keep reading have really brought light to this pill. everyone i know thinks im going crazy and i know i am. i have never complained so much in my life about how bad i feel and its on a daily basis for me now! im going to stop at the end of this month hopefully ill feel ten times better then i have been. i want my old self back!!! im so glad i took the time to find out about my bc and its side effects and all the post i have read about this horrible pill. it feels great knowing im not the only one!
