Need Advice! 2 Miscarriages!

Br

We have a 3 year old son- no issues getting pregnant or staying pregnant with him. I have had 2 miscarriages since starting to try last June. One was a late missed miscarriage with a D&C in September and then a natural miscarriage in February 2021. Any suggestions or things I should advocate for? We are doing a test for blood clotting disorders and starting baby aspirin and progesterone when a positive test. Any other advice or things to advocate for??
