So discouraged...

My husband and I have been trying to conceive for at least 4 years now. When I say TTC, I came off birth control and we weren't using protection. I began using this app to track things a little over a year ago. The only time I've had regular periods was when I was on BC. As of today, I'm over a week late from when my predicted AF date was. I've been nauseous for over a week, when I eat, in the mornings, etc. Broke down and picked a test up on my way home, appears to be negative. My heart hurts! I'm so dejected-to the point of giving up. I've never wanted anything more than to be a mom. My husband has a daughter with his ex (and she had miscarriages with at least 2-3 more), so I feel like I'm the failure here. Fertility treatments aren't really an option for us... Just really needed to vent.
