I had a 3 day period on November 6th. On Tuesday of this week CD17 I started brown spotting for a day and on Wednesday it turned to dark/bright red and had to use pads. Yesterday, I was back to brown/red spotting when I wiped. All spotting is now gone. Still trying to determine if this was implantation bleeding.  I took a test this morning with my second morning urine as my first was at 4 am. Can anyone see a line?? Also my periods are normal 28 days and have been regular, normally lasting for 4-5days and heavy.
