Low progesterone

So my new doctor (I got after the miscarriage) has ran tests and been so thorough since I started going to him last month. He is doing things I never had with my other doctor and I feel so well taken care of. He seems to genuinely care, and he remembers you which is really nice. He called me today and informed me of why I probably miscarried and why I'm having trouble concieving. I have low progesterone. My level was a 5 when he likes it to be in the double digits. The more I read the more I keep thinking how easy of a fix it seems to be, and it makes me so mad my other doctor never bothered to check. I could have possibly maintained my pregnancy if this had been discovered. I know nothing can be done now, but this is so frustrating to know. And for anyone having trouble concieving in the area of wv/va go to Randy Brodnik, he is Bluefield. I am so glad I switched over to him :)
