Did anyone get testing done after 2 miscarriages? What kind of testing?

Every doctor I have been to says they dont do testing until after 3 miscarriages.

Only one doctor actually tested the tissue and said its not molar related, and instead was just “random”... “nothing was found”.

So now what? Us women are supposed to just keep trying until one works out? This sounds so cruel to me😥 its been 8 months and it still affects me.

Did anyone else have 2 miscarriages and was not able to get testing done? Did your next pregnancy become successful?
