Join the convo if your AF is due July 20!

Sarina
So my AF is due July 20 and yesterday (July 12) and today (July 13) I got dark brown spotting! There is a chance this could be implantation bleeding! I don't have any other explanation for it just yet since I never spot. But anyways, either than the spotting, I do not have any other symptoms. But I feel like the spotting is a decent symptom but maybe thats just me.
What are you all feeling??
