Second miscarriage in 5 months

C

I just had a chemical pregnancy.

I had a miscarriage at 11 weeks in June.

All this after having a successful pregnancy 5 years ago almost (with a different partner).

I’m now almost 34...

What’s wrong with me???

Is it us? Are we a bad fit?

Am I too old?

I feel broken. I feel like we will never stay pregnant and im becoming scared to try again.
