Light pink spotting

Ok according to my two <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> I’m supposed to start either today or tomorrow. I just started spotting really light pink blood and it was only 4 little drops then I wiped and there was nothing! I’ve never had this happen before. Below are pictures of my cycle and symptoms and my temp chart. I did miss a few days of my temping. Should I take a test in the morning?
