On Wednesday I got a faint positive. Thursday it was darker. I started bleeding so I went to the emergency room and they said my hcg was 0. And I got a false positive but to keep testing. Yesterday I got another positive. I called my doctor and they said the blood test is 99%accurate. Today the line is darker than yesterday. Wth
