Clomid

My husband and I have been TTC for 15 months now. This past cycle I started clomid at 50, did the ultrasound, doctor said follicles are too small, lets try again next month with clomid at 100. My heart hurts, I'm so depressed I really thought clomid would have worked the first time around! Now Im just trying to pick myself back up and start all over again since this month was yet another bust! Its starting to get harder & harder every month to pick myself back up, my poor husband how he has to put up with me each month we fail!!  
Any advice tips tricks, or usage with clomid would be greatly appreciated!!! 
Im really nervous to increase the dosage and what kind of side effects it could have!
Thanks everyone!
