Can't stop crying

My husband is gone in the field for 2weeks (army). We've been trying for 2years for baby 1! This month I honestly thought it would happen. 2ppsitives 6negatives. My AF is due the 20th. I'm sitting here on the couch just crying. I can't stop crying. All day and night I'm crying. I'm praying everything. My husband calls every night around 11pm before he goes to bed and the first thing he asks is if I'm pregnant. Breaks my heart to disappoint him. He wants a son or daughter as much as I do. I can't handle this anymore.
