Welcome to our group wantingagirl!
I have 7 or 8 ICs and a digi CB with week indicator at home, waiting to be used. When I get my BFP, I will be testing every second day to see line progression. I caught my chemical early last time I was pregnant. Lines just weren't progressing.
AF is a day late so I'm mildly hopeful. My LP is usually 11 days but I've had a 13 day LP twice in the last 6 months so that might be why it's late. I'll test on Thursday if AF doesn't show.
