Dropping hcg levels

Last Friday (5 weeks exactly) my hcg was 292.7. I was retested yesterday and it dropped 50 points.. The doctors think I'm having an early miscarriage. Still holding hope because I still feel pregnant. I go in tomorrow for another blood draw and I am hoping and praying for good numbers. I just hate the not knowing. 😞 
Has anyone experienced this with a good outcome to a healthy baby?
