Disheartened ttc

I’m now 40. In the last year I’ve had 2 miscarriages. Both have been an empty sac and I’ve had d+c. I’ve had blood tests to check for coagulation and autoimmune disorders and check for perimenopause.

Everything is normal.

We have now been ttc for 5 months since last miscarriage with no success and even if we did get a positive I’m worried of another empty sac miscarriage.

Anyone else had similar problem?
