So this month I am beginning to start tracking my obvulation I ordered a pack of pregmate ovulating kit please if someone can instruct me on how to do this I have an idea but I want to make sure I do it correctly thank you in advance!!

Also when the test line is as dark or darker then control line does that mean I’m about to obvulate or obvulation already passed or should I bd a lot with in that time ??
