Feeling hopeless

I’m 43, I do have kids but have lost a couple babies in the past few years. My dr told my husband and I after our miscarriage aprox one year ago I’m clear to try. I been trying with different apps and ovulation tests and the past 9 months or so no luck. I am losing hope and feeling very disappointed in my body! We do have an age cap so we have no mutual kids, he has none of his own and I dream of giving him one and me having just ONE MORE... I am praying it isn’t my age.. idk what to do or how to feel anymore it just kills my spirit!
