I've been trying to stop POAS but I caved. AF is due 2-8. I've been crampy like she's coming. I took a first response a few days a go and I got a BFN. Yesterday I took a dollar tree test and it was BFN. I waited the 2 minute window and left it on the counter. Today I went to throw it out and I saw a line. Idk if it was a evap line but it was visible. I decided to take another test  (bottom test) and it said BFP!
