ovulation help!!!!

so glow changed my ovulation date!!!

Does this mean I missed my peak? The 6ths is when my test showed peak, but my period was 9 days late so glow changed the ovulation date, now my other ovulation date is changed and I didnt buy any test this month cause I was going to just go by cm.

My cm the 11th showed ovulation. I have been cramping since my two day period cause I'm not counting Saturday it started as just spotting and was late at night. I also spotted a few times so I tested a few times and all but one were bfn havent tested in a week cause I got tired of bfn. My next question is when did I ovulate, when should I be testing, and should I consider af to be here next week or as shown? Sorry in advance for all the questions new to ttc, (other two were unplanned) and new to a period again. Had mirena removed in june and it was in for 3 years, had spotting the hole time I was on mirena.

my slight positive
