Hi all! So I'm now on CD31, was supposed to get AF Saturday(2-25) today is February 27th..I normally spot 2-3 days before AF and NOTHING...been ttc since September..I used OPKS this month and thought I had a positive on the 7th but then on the 19th and 20th had a stronger positive(cd23-cd24) of course we BDed on 8th and on the 20th..anyways no sign of AF decided to take a test because I'm obsessed with poas lately and this is what I got?! Any advice would be great...
