How much does placement affect charting?

So I realized that I haven't been placing the bbt in the same consistent place. I do it orally but on the day of my dip, I was kinda drowsy and just put it in the front under my tongue. I remember that the beeping woke me a bit and startled me. I was more awake on the day of the rise though. My opk was definitely positive this morning but I felt like it could have been positive last night (I marked it as positive but I just wasn't 100% sure). My CM is now heavy EWCM but my CP is high, not open but not closed and a medium firm. Yesterday my CP was High, Closed/open and soft but I had watery CM that was a little EWCM toward the end of the night. About 2:30a I had ovulation cramping (the traditional stabbing/pinching cramps) on my left side). They did wake me. They have been like that on and off through the day and now I am getting it on the right side but not as intense. So did I ovulate or not? I'm a bit confused. Glow is predicting that I am ovulating today. Sorry I am so confused!
