I'm so depressed

Me and my boyfriend have been trying for a year now , and still nothing 2 months ago in had a positive test then 3 weeks later a negative on every single test , I lost hope and faith I think I became bitter now getting my hopes up and him wanting a baby so bad I'm done.

I never thought 32 and still no kids . My mom had me when she was 40 but my biggest fear is I wont have any. I've giving up. I'm to depressed to even look at every single pregnant women now without busting up crying. I feel like I failed or failed my boyfriend.
