So I'm looking for some answers. I've had 5/6 positive OPKs in a row. On May 1st and second it was super dark red in the test line but it was looking positive before that and still does!! I don't understand, what's going on? The first picture is when it started looking positive. The last 2 both looked equally dark as the control... I changed brands today and it still looks positive! Am I going crazy?
