Help!! What the heck is going on with my body!?!?

So my period is three days late which is kind of unusual. Usually it’s only about a day or two and all my pregnancy tests have been negative or evaps. The past day I’ve been spotting a little bit but I have to basically check my cervix with the toilet paper to even see it. Has anyone ever been through anything like this?? My body has never been this weird before. I’ll add pictures of what the spotting looks like and the tests...any advice or personal experiences would be extremely helpful and appreciated!
