please help! so confused!

Ok so for the last 3 months I've been taking ovulation tests with a positive every month. this month all of a sudden I have yet to get a positive. when I take a ovulation test theres not even a second line there.. usually by now I have a faint test line. my estimated ovulation day is in 3 days and nothing yet. I also have pcos so that may be why. I'm August I had a cyst rupture so I'm just concerned that my body has yet again developed another cysts. any info would help at this point.
