Ovulation confusion

New to these ovulation tests and so confused! I had a positive last night about 10.30pm & this morning at 7.30am. I’ve disregarded the morning one I’ve been told it can give false positives. Howrver tested 11.45am following day, today and it’s negative (I think) I’ll post pics of last night and late morning today. Does this mean I’m ovulating still? I will test later tonight. I do have pcos I don’t know if that makes a difference?
