AF due Dec 25/26!

Shannon

as stated above , af is due Christmas day or boxing day . However* I had a very light and abnormally short visit Nov 25th-29th (i usually have a perfectly awful heavy 7 days lol, where as this time 25th and 26th as usual, 27th spotting, 28th nothing and 29th spotting again) And from December 12 to today dec 16th I have been having dark brown spotting . Has anyone experienced this? Is there the even the slightest chance I could be pregnant? my husband and I have been trying for 8 months..
