Hi H.,
I know you must be very stressed, I don't want to stress you more but I felt it's important to share my experience with you. My sister recently had her first miscarriage. She was not actually "trying" for another baby but when she went in for blood work, she got similar results as you. I believe her levels were 27 and the OB told her straight up, it doesn't look good. About a day or two later she miscarried......
I've had 2 miscarriages and 3 healthy pregnancies. With one miscarriage, my levels got as high as 1000 before I lost the baby. With my second, I didn't even get a chance to get lab done before miscarrying. However, after doing my lab with my 3rd (healthy pregnancy) my results were around 250 and I remember the nurse telling me I was approx 2-3 weeks along. I honestly thought I would miscarry with my numbers being so low but I did not and I had a wonderful pregnancy.
Hang in there and if you happen to miscarry keep the faith strong and be confident that you will have another baby. I wish you the best and please do keep us updated!
