2 days ago I took a dollar store test, it was a BFN. So this morning, I went to Walmart and went ahead and got the first response (2 pack). I only took one, with morning urine. I def. see a very faint line, but I'm not sure if it's an evap or not. It came on the screen within 2 mins and hasn't faded any. If it was indeed a faint positive, how long should I wait to retest for a darker line? Like how long does it take for the HCG to build back up? I spent like $10 on two, so I don't want to take it too soon.
Wait a couple days. I took my first test the day I was supposed to get my period and the 2nd line showed up instantly but it was faint. I waited 2 more days took another and that time it was really dark..I took another one the next day just to be sure lol
