Question?

Roxanne • 25 years old. Married. Mother of two and another on the way... 🙏🏽
So I have a question.. my last AF WAS August 12... I haven't got a positive yet.. but I had some brown spotting at night on Sept. 22.. and very light pink when I wiped in the morning on Sept. 23.. so could that mean I implanted that day and the reason why I'm not getting a positive because I'm too early
