I ovulated on the 8th. I have had some spotting on the 17th and I thought af was coming early. I did an opk which is showing positive, tired one of the cheap tests and kind of see a line, did clear blue early detection and the line is so faint I’m convinced it is an evaporation line. (It did appear within 5 minutes) I am not due till the 28th I know it’s still early but was expecting the line on early detection clear blue to be slightly darker. What do u guys think?
