The same night I took that HPT (Home Pregnancy Test) after I had some spotting a few days following a 14 day Flo – something really weird happened! EVAPORATION LINE OR POSITIVE TEST??
So my friend who had an extremely long cycle and thought she may be Pregnant before AF (Aunt Flo) reared her ugly face, wanted to see if urine CONCENTRATED with Menstrual Blood would affect the outcome of a HPT? Well, just so happened we also had 2 Negative HPT’s lying around and we thought it would be fun to see if AF could (also) effect a Negative HPT?
