Feeling discouraged!

Amanda
Me and my husband are on round 3 of clomid with increases in dosages every round for baby # 1. We have been trying for 4 years. We have miscarried twice, but they have found the problem for the miscarriages and now the fertility drugs don't want to work. Feeling like i want to give up on the whole thing. I am tired, depressed, emotional, and stressed. Any suggestions?
