Hi all i have a question.

I have just started using ovulation testing kits. I started last thursday and the first one didnt show any test line so i assumed i wasnt ovulating. I tested again on friday and both lines were the same colour. I tested on saturday and the test line was darker than the control line. Tested on sunday and the same thing. Now its monday and i tested to see what would come up and the test line is still darker than the control line. That means i have had a positive test for 4 days. Is this normal? Im scared im going to miss my fertile window wven though hubbya dn i have BD on saturday and sunday (and probably again today now i have another positive test)

Has anyone else experienced this?
