Hi ladies , me and my SO have been ttc for 1yr & 1/2 now but this cycle we/I decided would track with OPK so I got first response , I started tracking 3 days ago . First day of my fertile window 12/4 I tested no lines showed ( expected ) 12/5 I tested and two lines popped up one was faint ( if you can see it in the picture) and today 12/6 I tested after work and the second faint line I had yesterday is no longer there and it has me confused as I thought the lines get darker as you are coming close to ovulation glow said I ovulate dec 9th but dec 8th is an important day for me . Im just wondering why the line is no longer there ? If you ladies could give me some advice or insight if this has happened to you before I'd greatly appreciate it Thanks!!!! .
