Ovulating with PCOS?

I was diagnosed with PCOS after I was already pregnant. My hubby and I were trying for a year, we saw an OB, she discovered I have PCOS and we were discussing options. But little did I know we were lucky enough to already been (at the time only 2 or 3 weeks) pregnant. So we didn’t really any options to consider anymore, because we already conceived. Now we are wanting to try for another baby. But knowing I have PCOS I don’t really know much about it..I know my periods are never consistent, does that mean ovulation is never consistent? I track all my periods on Glow and it gives me a time I SHOULD be ovulating, but does anyone know how accurate that is? Or is there any other way to know when I’m ovulating?

Someone please help.
