cd8 spotting after checking CP

So here is my chart, got my thermometer today so ill be temping starting tomorrow, but I'm on cd 8 went to check my cervix position and noticed some spotting but I've not had any on toilet paper when I've wiped all day. I'm super gentle when i check. do I consider it a spotting day too? it's brown, but only noticed it when i checked my cervix position. now [about 30minutes later] went to the bathroom and wiped and saw the brown spotting for the first time all day, but I'm so aggravated that I'm still getting it. it was a super short and light af compared to previous cycles. but I did have my nexplanon removed Nov 2. had a regular cycle the next day. Dr confirmed ovulation last cycle as well. so I'm totally lost lol. I just want to know why in the world am I still spotting. like I just want to dtd lol do you think it's just irritated cervix, or residual af, or what? uhhhhh help please :)
