Low Sperm Count

My husband and I have been trying to have a baby for the past 4 years. We’ve had two miscarriages that were both within the first 8-12 weeks. I am considering a sperm donor just because he has an extremely weak sperm count. We’ve talked about it before and he was 100% down for it as long as it was an anonymous donor. However, we decided to give it one more year before we go though that process. Unfortunately, I, being an emotional mess over the whole situation, don’t want to wait. What would you do?
