low progesterone

I had low progesterone with my first pregnancy which they gave me supplements and everything ended up fine, I am experiencing a chemical pregnancy right now which I've done a ton of research and it says often caused by low progesterone. And all of the symptoms of low progesterone I have. My thing is I feel like my doctors should put me on progesterone now because I read you'll have trouble getting pregnant with low progesterone and so when I do get pregnant again I have a better chance of it being successful. But my doctors aren't doing anything about it, should I find a new doctor? Or will they all not do anything?
