what do you ladies think

Amy Jo
I have normal 29-30 day cycles
LMP was September 23
Was suppose to start October 22
Started spotting October 13   (cd21)
Stop spotting October 30  (18 days)
(cd38 from LMP) 
Spotting only enough to wear panty liner. But only really there when wiping.
Been experiencing very very mild cramping nothing compared to when I have AF
Took PG test on
Oct 27  - neg
Oct 30. - neg
Nov 4    - neg
AF could start
November 12 or 
November 21
I figure if AF does not come by this weekend I will try testing again
But I just don't know what to think of this
