Ok, the picture below are my strips. From right to left I did one Thursday,Saturday, Monday, and today. I didn't do one Sunday and Glow says I OPK on thatbsaturday which is the darkest line. We did the BD Thursday and Saturday and then Monday. Do you think our chances are good? After my mc this is the only app that says that week was my fertile week! And sure enough I surged then. Only thing is why are the lines not super dark? 😁 all help appreciated!
