For those battling infertility.. what tests have you had done?

I have had recurrent miscarriages and no successful pregnancy

They tested my thyroid but it came back normal

And my last pregnancy I was on progesterone and baby aspirin but I still miscarried

I conceived on my first round of clomid since I hadn’t gotten pregnant a year of trying after the previous loss. Just to miscarry again was heartbreaking especially since I was on progesterone and baby aspirin! I really thought it would be successful

3 missed miscarriages in the 6th week

2 early losses

My midwife doesn’t seem that knowledgeable on what tests should be run and said I can have any tests I would like done

But I’m not a fertility expert and don’t know what to look for

Anyone have any ideas on what tests to run?

Or should I just see a fertility specialist?
