3 miscarriages

I will be 37 in march and am currently on my 3rd mc. My dr recommended I see a specialist as I can’t seem to make it past the 6 week mark. Has anyone had several mc and got pregnant again and made it full term? What can I expect if I see this specialist? I am just worried it’ll be really expensive and I don’t know we can afford it 😒 I just really want to have a baby and start a family with my hubby.
