Implanting question.

Hello I have only been using glow sense January. I follow my days and have intercourse on my most fertile days. I have been a little on and off with my temp recording due to work. I noticed with different symptoms after my fertile window changed randomly. I have felt sick and have a stuffy/runny nose, tender breast and I started spotting pink Monday pink/brown Tuesday wed wasn't much today pink again it's light. I noticed glow prefix my period differently next month too, I always start AF from 1-3 off the month. I wonder if I am implanting and I pray it is a baby growing! Anyone have anything like this ?? I am going to wait to test for a few more days.   -Amber
