Medications for IUI

So long story short... I initially was on Clomid and it made me hyper-stimulate to a point where I got placed on bed rest and insemination was canceled. I had a total of like 20 follicles develop and they estimated about 8 eggs would be released. So now I am on femera.. I have only made 1-2 not so great follicles on 4 cycles of being on it. They are talking about trying Gonal-F. We have had 4 failed IUI cycles on the Femara. We quit trying 2 years ago and have just started again.... was just wondering for those that have tried Gonal-F injections, what kind of side effects did you have? Was it worth it for the increased price of the medication? Any insight would be great... Thank you!!!
