So confused

✨M

So last week I got this. But apparently it was false or whatever because I got my period the next day. My period was a little heavy at first and then it became so light I didn't even need to put a tampon in. Which never happens. Glow is always on point with my period and this time it was a day late. And now my period has stopped. Wtf is going on with me 😥😥😥 please help my period is always 6 days but it lasted barely 4 1/2 days.
