Do you think I should even bother testing?

Let me premise this by stating that I have wasted so much money on first responses and internet cheapies that I am embarrassed by it lol. Since my D&C for my last loss at the beginning of March my cycles have been beautiful, 28 days, more regular than I’ve been in a very long time. But this month I got what I’m assuming is my period 3 days early. It wasn’t actually due until today. I didn’t think too much of it, except that it has yet to progress to anything other than heavy spotting...it’s there and red when I check my cervix and pink when I wipe but literally nothing has made it to a pad. No clots, and three days in I would expect it to be heavier by now. AND even stranger for me my bbt hasn’t dropped yet. By three days into my period its normally already majorly dipped. Should I even bother going out and buying more tests? Or should I just wait and see if it gets heavier?
