Anyone have any success stories of a low beta at 15dpo and it leading to a full term pregnancy?

I’ve had 6 miscarriages, 5 of which have been from fertility treatments over the last couple years. I miraculously fell pregnant this cycle with no treatment (which should happen considering I have no known issues) but unfortunately my beta came back very low today; 16 to be exact.

I know it’s not looking good, looking to see if anyone can bring just a bit of hope my way 🤞🏽
