I took a test this morning but of course it was a defective test! I'm really not 100% sure when I should be testing. I have 3 apps predicting my period to start Jan 28 monday, and one saying Feb 1st. I KNOW I OV the 17th or 18th, both days were +OPK, With the 18th being the darkest. However any "period predictor " site I use puts my OV date before that (which I know to be inaccurate.) Ugh, I just want to know already! Annie have you taken another yet today?
