Hey ladies! Any advice on this? I started testing last Friday and it was a vvv faint line. I have been testing all week using pregmate strips mostly and a couple of days I used the clear blue test. Both clear blue tests came back negative. The line seems like it has gotten darker but it’s staying the same. Did I maybe miss my peak already or maybe not ovulated yet? The last 5 pictured are all from yesterday & today.
