Let's talk periods...

My question is, can you still ovulate even if you miss your period one month (my cycle is never regular). My period was supposed to start on August 21 and I last had it July 2, and it didn't come. I got a positive opk on August 11. However I have taken many preg tests and still no positive. So I know I'm not pregnant but even though my period is late can I ovulate again now this month even though my period never came?
