6dpt and negative

My transfer was last Thursday, so I think I’m 6 days past it (not counting Thursday ). Took a test today and it was negative. I’m supposed to go for my beta Monday. Do I Still have a chance ? This will be my second failed ivf if it doesn’t work. I don’t get it....

We have 2 more embryos , but I don’t know if I can do this again. Maybe I just transfer both even though I don’t want twins.
