Ovulation predictor tested positive for four days?

Question

is that normal. I thought it was only supposed to show positive for a 48 hour period. This is probably a stupid question, but I would appreciate the help.

Answer 1

It's possible considering normally a woman is most fertile 3-5 days before ovulation. It's best to have the sperm waiting for the egg to be released. Sperm can live up to 5 days in a woman if the conditions (cervical fluid) are right.

Answer 2

I had it show up for three days this month, I thought it was odd as well. The first one was darkest and the others were lighter and lighter.
