Help please

Okay so I’m 5 days late which isn’t unusual for me. My periods are usually 24-39 days between each cycle so it’s not a big deal that I’m late but what is bothering me is a few days before the app said it was time for me to start I had some rust color when I wiped. I say rust color cause it wasn’t bright and it wasn’t light. It was an in between color and it lasted only a couple of hours because the next time I went it was gone. Any one else have this happen and is it normal?
