Looking for some positivity

We just found out that my husband will be headed to boot camp December 1st instead of January 26th. I am sick to my stomach with worry now. We always planned to get pregnant before he left. That plan started six months ago. We now only have one more fertile window before he leaves. Once he is gone we can't try again for 3+ months. We also just found out DH count is low. The pressure and loss of hope I'm feeling right now is consuming me. Any words of encouragement would be appreciate.
