Just a quick question about pcos and ultrasound....

K

I suspect I have pcos but my ultrasound was clear. I’ve been pregnant 4 times and one ended in Mc. Gotten pregnant easily in the past. Ttc for 8 months now. Chemical 6 months ago. I have somewhat irregular periods. They come every 4-6 weeks. My question is, and I know I can still have pcos with a clear ultrasound, but since I had a clear ultrasound, does that mean I ovulate? Or what could that mean?
