Hey babyblue, looks like we're on a similar cycle! I'm CD19 today and most likely 6dpo. af's due around the 25th though but I'm not 100% sure of my cycle length (last month was 25 days, the month before 27).
I have had some very slight cramps on the left hand side (had O cramps last weekend on left hand side too) yesterday and today so fx its implantation, .
I'll probably test on the 24th or maybe hold off until after next weekend if I can!
