Sad day

Just was in for IUI #3. DH only had 3.6mill sperm. Wtf. How can that be? I'm so incredibly disappointed. He usually has twice that and we've had no luck so I'm really pessimistic about this go 'round. I feel like it was a huge waste of time, energy, emotions, etc. I have 4 large, mature follicles that are ready to be cracked and now I feel like it's going to be another fail. Another BFN. Another cycle of trying not to give up hope and cry the whole time. I'm so disappointed. I hate this!
