21 DPO, CD 40, and a week late this last Monday. No sign of AF and having various symptoms. Took a test first day, third day, and another one mon Monday (a week late) all BFNS. Idk what to do. I'm never this late. Even my husband says he noticed things like my mood and such. Guess I'll just wait and if AF doesn't show by Monday (2 weeks) I'll go to the doc.
