Confused help!

Hey girls! So I’ve been having spotting (as you see below in the picture) for about 2 weeks and it’s everyday. It’s about the same amount and btw it’s super lighter in person than in the picture (it looks 10x darker in the photo.) I’m on a combination pill an take it every day literally at the same time and I’ve been on it for about 4 months. Me and my fiancé do have unprotected sex often but we’ve slowed down since I’ve been so paranoid about this. I’m having no pregnancy symptoms or really any period symptoms. 2 negative pregnancy test. What is this? I want to be able to not wear a pad and worry anymore 🤦🏽‍♀️
