What were your hcg levels 4-6weeks

I know yall are probably annoyed with my posts... but i go back tomm for more bloodwork and just looking for a weeee bit of hope ig you could say.. my hcg was 287 and im anywhere between 5-6 weeks. My periods are wack and longer sooo ive gotten a few different due dates .. anyways, we are yet to see anything on ultrasounds.. hospital told me i could have implanted late and im in earrrly pregnancy or its the ending of one. Has this happened to anybody else?
