IUI- Fail

Had our first IUI and had spotting yesterday thought maybe it was implantation since it was early. Took a test today and negative. My heart is literally aching. I know it was crazy to think IUI would work on the first time but I was hoping and praying!! The problem now is money and time. My husband is gone during my fertile time next month and possibly the month after. I know life goes on but it's so hard. This is month 18 of trying. I know people go years and years but i am so heartbroken.
