spotting since cd20....

Jamie • Wife. Nurse. Mother of one little boy 💙
I'm on cd23, 7dpo and have been spotting for 3 days now.... and my period isn't due for another 6-7 days.... it's dark brown, but sometimes has a reddish color to it. I thought it was implantation bleeding, but this seems like to long and it's every time I wipe I get something, but not enough for a pad or tampon. What is going on? I realize it could be AF or the start but I haven't had cramps and my boobs and nipples( they never hurt during AF) are so soar.... ugh has ANYONE experienced this? I had some ovary cramping days back, but since than it's went away. Please help!
