Faint positive at 6 weeks at dr

Kerry
I went for my first ob visit and first thing she tells me is my test was a faint positive. I am so worried now! She told me not to be because I am only 6 weeks and that can happen. Did blood work and checking hcg levels which I will get in the morning. So stressful! I've tested positive at home since just 3 weeks and a day.
