I don't seem to be getting this at all. I am really new to ovulation tracking and have started with test strips - dipping strip into glass with pee. I have been tracking since CD2 and have a couple with faint positive lines and then the most two a very very faint line. I suppose I am looking for some advice, when should I start tracking or is it best to do it every day / how often / at what time? These are cheap test strips, is it worthwhile buying another type? The ultimate Question is how do you know when you are in the ovulation window and is it possible to tell how long the window for conception? Any help is much appreciated! I am trying to understand mine as precise as possible for IUI
