I got my period 8 days ago lasted 5 days 3 light 2 super heavy. Heavier than I've had in a long time. Tested like all serial testers before af and negative. Day 2 was really heavy but I have ecwm it seemed during period. So I used a opk as soon as bleeding stopped, they all been positive. Yesterday I used a hcg test like a crazy person a almost invisible line. Today the line is darker. Anyone ever have this happen. I'm also tried a diff brand today and a very faint line.!! Go figure.. Cause I cant. We have been trying 3 years, had 5 chemicals never has this happened
