I got my period June 24th -25th, it is normal for me to only have it for a few days. My period is very regular so I was supposed ti get it around that time. Today, July 5th I went to the restroom, wiped and there was some blood. Is it possible that my period started up again

Yeah, your period is unpredictable, you may think you have it down, but un stable for first2 years.
