Spotting??

Jacklynn💚 • Hey y`all! I`m Jacky! Married 7/26/2015! TTC #1!! I`m a Veterinary Technician in California! Hoping to make new friends!
So I started my period on the 29th it was light. The 1st was heavy and the 2nd was light on my first tampon and then the next 2 tampons I used came out clean and no spotting or anything until now the evening of the 3rd. That has never happened before just wondering if could be spotting in early pregnancy or just a period??
