Anyone have "missed miscarriages "?

Destiny • I`m destiny, my so and I have had two miscarriages and then 1 chemical pregnancy/mc I have a beautiful healthy 4.5year old. My wife and I are trying for baby number 2.
I have had two along with another miscarriage.
It's when the baby stops developing very early on but you don't find out until later.
My last one was 3.5 yrs ago and we have been ttc again for 5 months.
Did any of you go on to have a healthy pregnancy? Did they find out why for you? Find a way to fix it?
Thank you for your responses!
