Late menstruation

Hi everyone!

Right now, I’m having a late menstruation. Based on this app, I should’ve got mine 3 days ago. 2 days ago, I got some brown spots and I thought it was a beginning of my period. But the next day, it stopped and there’s no blood. It’s empty. In the night, the brown spots come again and it repeats that there’s no blood on my tampon today and it’s literally empty.

Anyone ever having this kind of situation?🥺🥺
