Re: most sensitive test
I swear by First Response. With my first baby, I tested several days before AF was due and got a faint positive. I went to the doctor the next day to confirm but their urine test showed nothing. The doc said that you *never* get a false positive so they did a blood serum test which was a very faint positive. They sent the blood off for an HCG count and it was only 50...the doc couldn't believe than a HPT picked that up. And I got that one because it was the cheapest thing at the store!
