What is this??? 😑

So I’m am kinda confused on what this pink/bloody discharge is. It started yesterday & is progressively getting a bit heavier. There is no smell & the discharge isn’t enough for me to need a tampon or party liner. I’ve had mild discomfort( I wouldn’t even call it cramps, just my stomach feels off). My period isn’t schedule to start until February 4th or so and I am very regular with my cycle so that is why I’m confused what this could be. I am on birth control and not ttc. I did take a digital test that is negative but after reading up on it, I’m scared it could be implantation bleeding. Thanks in advance for any advice with this.
