New here and DH has low sperm count.

Anyone else in the same boat as I? Dh has 1 million sperm motility. He goes to the urologist next week. We quit trying trying after many months of bfn's and false hope with false positive and late af. He's military so he's just now being able to get an appointment. The only thing is, as bad as I want to be a mother and he a father, he is deploying in June to Afghanistan, 5 months from now to the most dangerous place there since he is infantry. So if I do get a bfp before he leaves, I will be experiencing pregnancy by myself and I want it to be a bonding experience for both of us since we are ttc baby #1. What do you guys think? As much as he would want to be apart of the experience, he wants to start trying trying again after he gets another test done at the urologists. The way he explained it to me was, "If I don't come back, I want you to be the mother of my child even if I'm not around." Any opinions? Advice? Thanks!(:
