Ovulation

Hi everyone, I was diagnosed with PCOS and do not ovulate on my own. I have done 1 round of clomid 50mg(unsuccessful), 1 round of 100mg(ovulated,not pregnant), another of 100mg (unsuccessful), and I am nearing my fertile window now after taking 150mg.

On the 50mg & 2nd round of 100mg, when using the opk clear blue digital, I got blinking smileys and then nothing. Anyone know why I would get blinking smileys if I never ovulated? I had the blinking smiley and then solid the 1 time I did ovulate.

Does anyone have any suggestions for me? I have been taking opk’s for about the last 5 days and have had no luck. I’m worried I won’t ovulate again this month 😩 not sure what to do. Been TTC for well over a year...
