TTC after 2 losses.

I am a 38 year old mother of two. I had my kids when I was very young and never had any issues. I got married about 2 years ago and my husband does not have any kids. We have had 2 MC this year already. I want to try again but he really isn't into it. I am getting really down since I can't seem to stay pregnant. I have searched online to see what I can do to increase my chances but there really isn't anything I can find. I also read that is uncommon to have back to back MC's. Am I too old for this.... feeling so depressed. just want a rainbow baby but afraid to be disappointed again.
