Need HELP Ladies Please

So I was supposed to ovulate the 16th. Glow is normally correct within a day or two. I took 2 different clearblue advanced digital ovulation test everyday. I got my first high on the 12th. I had 7 days of high so I quit taking the test thinking I wasn’t gonna ovulate. I took another one yesterday and it showed peak. Took another to see what it said and peak again. So it’s saying that I would be ovulating today. My CM is like gummy, thick and nothing like the watery kind I get around time I ovulate. I had the watery CM last week and stretchy CM when I started to have high results on the test. Does this mean that I just ovulated super late and is it possible to get so many high days or could it possibly have missed my peak and the 2 test from yesterday are actually picking up implantation?
