Today is CD 32 and this is totally out of the ordinary. cycle is usually 25 to 27 days. I took a test on Tuesday and it was a bfn. Now a few apps are saying I am 3 days late but I was expecting AF the 20th so I thought but it's still not here. Have any of you ladies tested bfn and then later a bfp?
