Do u have a regular 28 day cycle??

Ok, im 34 & no children (yet)

I have had a regular 28 day cycle since I started my cycle at 12 yes old. She comes rain sleet or snow! Always in time. On the 12th a few days ago, after falling asleep in my car at the park 👀, I went home to use the restroom, when i wiped, I saw light blood, im like dammit, this bitch is early... So I opend my app and this bitch isn't due for another 7 days.. Ok, so I was still very groggy, I put a pad on and went to work. I went to the restroom after a couple hours and there was only about 3 drops of brown blood on the pad, I assumed it was dried up hence the color, but when I woke up I Had no spots or anything after I wiped. So on the 13th, I don't have anything til I wiped which was close to the end of the day. The 14th, I wiped tan/brown after I took a bath. Went to work, liner again had a streak of brown on it. This morning nothing after I wipe. Anyone experience this with a regular on time cycle like me?
