Period or early preg spotting


My last real period was oct 5th. I started spotting on oct 27 - Nov 1. My boobs have been so full and achy. I had no cramps with the first spotting. Now 2 days ago I started spotting again & idk what to think... it’s no where near reg period bleeding and my cramps are not like my normal wave of pain just in one spot and barely there, some times sharp twinges but more pressure like feeling.
