I am pregnant with my 3rd child and had the first ultrasound last Friday along with blood test. This morning I get a call from the doctor at 7am telling me that she needs to talk to me about my test results. Apparently I tested positive for HIV. They are going to retest the blood sample that they have and call me back. They told me not to worry but how could I not??

I only have my husband and he's never seen anyone else. How could I have gotten it? I'm just a bundle of nerves. Had anyone had a false positive in the past? Is that possible?
