Suspected Chemical Turn Out Ok?

Has anyone had a suspected chemical pregnancy turn into a healthy baby? My doc’s office just called and my bHCG and progesterone are so low (11 and 1.9) they think it’s most likely a chemical but want me to start on progesterone supplements. Is there really any point? I’d rather have this end now than end in a miscarriage further along. If this isn’t meant to be, I’d rather let it go and start over.
