Could I be pregnant?

I’m overthinking a lot !!! I’m 12 dpo and had some really light spotting about 4 days ago, and went away now I’m having a little more spotting. Have been TTC, took a test and came out negative? Should I take another one tomorrow? Could I possibly be pregnant? Have been having cramps sore and swollen boobs, get nauseous when I eat certain food, and body aches. Is it to late to have implantation bleeding? Glow isn’t always right about my period but I should possibly be starting in 2 days.

This was my spotting today
