I have had 5 pregnancies with 2 little boys to show for it. I have diabetes which adds some extra complications into the mix but it was actually my endocrinologist that pushed for me to have testing if i lost another, i was currently pregnant with number 5 so they put me on a few extra things like high dose folate and low dose asprin and i had an early scan to see everything was ok. I carried him to term and had my tubes clipped as i couldn't deal with any more losses. Both my boys are perfectly healthy and happy.
I was 38 when I had my last and the ob did mention that as you age you can experience more miscarriages as the eggs are older and tend to have more chromosomal abnormalities.
I'm sorry for your losses and i hope you get your earthside baby soon
