Is any of this chart making sense?

Chart attached this time!
 I have been recording my morning bbt for two weeks taking it within seconds of waking up around the same time, Glow fertile time was 14th-20th Jan with the 18th Jan being my high % day - also agreeing with my cb fertility monitor, so that I'm pleased with. But is this chart telling me anything? Or should I not be really taking much notice until maybe 2 or 3 complete cycles??
