Rocky charts

So last month my chart was rocky due to not having an actual bbt thermometer but this month I’ve been using a bbt thermometer and my temps are still rocky! I always temp at the same time and my bbt thermometer is brand new. Does that mean I’m not ovulating at all? Should I start temping vag in my next cycle to see if there’s a difference?
