Is my hcg too low??

My blood hcg was 70 on Friday and I’m supposed to be 5 weeks. I do my second blood draw on Monday to see if it’s doubling but I don’t think it’s looking good 😩. Anyone had a positive outcome in similar situation? It’s very possible I ovulated and implanted late but I got my first VVFL a week ago so it doesn’t seem like my hcg is going as high as it should.
