JC
Okay !!! So AF was due on September 25th. No show .... Also no signs of her ... Boobs feel normal ... Just going about my day .... I Adjusted my stuff to show cycle 31 days to see if I could see my latest .... I never go past 30 days ... 99% of the time on 28 and 29th day depending on morning or night flow.....anyway surly she will come .... Well im 33 days into my cycle now and no AF.... So I took a test and 😩 BFN!!!! What the heck is going on ! 
My boobs usually hurt so bad 3 or so days before she gets here and nothing ! I've been peeing more than usual and have had some annoying lower back pain .... But still I get this !!!! Any help ? Or insight ?
