How long after your missed period did you get a positive HPT?

I have had the similar systoms to what you're saying. My period was about 7 days late but I always felt like it was coming on but never did. Started feeling light headed almost felt like I needed to throw up but never did. I took 7 HPT I got 4 positive and 3 negatives. So, I didn't know what to think so I went to my Dr. and took a blood test. And I got my results yesturday and it turned out that I am 5-6 weeks. So the best way out is going to your DR. and take a blood test. And your anxious days will end somehow....
