Follicles on ultrasound!

Vi

Didn’t get much feedback when I posted before. I went for an ultrasound yesterday and the tech said she saw multiple follicles. I got my positive opk on Sunday and Monday, she also said my endometrium lining was thick, I think I saw her measure it at 13.5mm. So if the follicles are still there, have I not ovulated yet?🤷🏻‍♀️
