Advice?

So, been having pregnancy symptoms such as nausea, light cramping, headaches, super tired, not really hungry, sensitive to smells, peeing a LOT! Tested 8/17 which was 3 days before my period was supposed to start, and got a negative. Started bleeding extremely lightly this morning.. not even enough to need a pad or tampon. Now I’m having clearish/whiteish/yellowish “discharge” instead of blood... should I wait until this “bleeding” stops and test again or just wait it out?
