I Need Insight

Je

Okay so I'm still learning. I've been trying to figure out if I ovulate late or not. My CM has been watery or EWCM yet this cycle, but from what I'm reading the temp will drop when you ovulate then raise for at least 3 days telling you you have ovulated. Am I correct? I'm just trying to pinpoint it and any insight is appreciated. My temps have been a roller coaster this month but it is the first month using a BTT thermometer.
