Anyone had anything similar

Hey girls 👋🏼

According to this app my period isn’t due until the 9th yesterday (5 day before) I woke up went to the toilet and when I wiped there was blood (enough for me to think my period had started early) and it was red anyway popped a tampon in and went about my day after about 4 hrs I went to change and pulled it out and literally a droplet of brown blood was on it and nothing else nothing since cervix is high and feels closer 🤷🏻‍♀️ has anyone had anything similar

Bloody period knows how to confuse me that’s for sure
