2 am can't sleep :( help please... Tmi picture.

Kimberly • 22 years old. Wife. Teacher. Went off birth control pills in January 2016 and TTC since. Baby dust for us all! ✨
This is my chart. And Also a picture of spotting I just experienced last night before bed. Only found it when I checked my cervix. I had very light spotting at 9 DPO as well. But it was very light brown/yellowish. Rather than the pinkish that this is. What do you ladies think. Could it be implantation? Anyone have spotting a day apart and it was implantation? AF is due tomorrow (Tuesday July 5th)
