what is a weak positive blood test?

I had taken the blood work yesterday and got the result as weakly positive and the doc did not reveal me the hcg level, she just asked me to wait for 1 - 2 weeks and then get the blood test again, i have taken home test and they were faint positive lines too but my af date is july 2, this means im still pregnant  right? Lil worried since she did not even say a word apart from asking me to wait n take the test
