after effects of long term treatments

Hey all you long time ttc'ers! Wanted to get some advice and hear others experience about an issue I am facing. We have done a year + of as of yet unsuccessful ivf/icsi and fet treatments, and after a chemical pregnancy which ended in a loss, just needed an emotional and physical reck. It has been 8 months now, and my cycle is still on a roller-coaster ride!!! I sometimes cycle my normal 4 1/2weeks, and then go 2 months, then 2 1/2, there is no way to know! Also it is heavy then light and crazy in between, which I never had before I started treatments. ( we need them bc of severe mf) I also have occasional sharp pains by my ovaries and generally weird feelings in the area. Is this normal? Do most non pcos women develop pcos as a result of all the medicine and surgeries? Is there anything to do about it? And, most importantly- does it get better with time or after a successful pregnancy/birth? I am only 25 and worried that I have messed up my reproductive organs permanently!:doh: Thanks again for sharing experiences or knowledge on the matter!!
