Low amh

I haven’t been tested but I think if I was it would be low. I was able to conceive my 2nd on clomid and went back on clomid and after 2 miscarriages and now I can’t even get pregnant I think AMH is a factor. I will be making an appt with a fertility specialist to confirm. Is there any way to solve it. I am high stressed person and I went years with undiagnosed low vitamin d. I probably went years with extremely low vitamin d.
