I'm cd41, 10 days late for af, my boobs are really sore and I've been feeling nauseous for 2 days. I've been using cheap strip tests from amazon and all have been negative. Did this test today and it immediately came out with a faint line that had a little bit of blue in. Then after 10 mins the line darkened a bit on the edge (I know after the time frame).
Is this an evap? I had a negative pink dye cheap strip test this morning.
