Am I testing too early?

TMI* About a week ago I thought I was starting my period, and was out of the loop for pregnancy this month. Yet it was only brown spotting, and stopped before the next day. I'm now currently 4 days late, and I've taken two cheap tests but both were negative. My boobs are super sore, and the veins in my boobs are super blue. Am I just testing too early? I know my last pregnancy (ended in mc), I didn't find out until 8 weeks.. 🤔🤔🤔
