Could this be a good sign?

So on the 6th I had some slight cramping in my lower abdomen that didn't last very long just a little bit throughout the day. And then yesterday I was having some light pink spotting all day with a little bit of dark and this morning when I woke up I went to the restroom and had some orange colored spotting with some pink in it. My period isn't due for another week and a half according to Glow. Also I've never really had spotting before not getting my hopes up for pregnancy because it can be anything. Just wanted to see if anyone else has had this happen to them and what it was. Today I have no sign of spotting and when I first woke up I was kinda nauseous. I feel like the app had my ovulation days wrong or something.
