Ultra sound during my ovulation week

So I had my Ultra sound done today, I was told that before you ovulate one of the follicles is a bit bigger and that is what indicates that it’s ready to release an egg. The tech told me she was unable to locate one that was a bigger size. She said that my cycle may be off but normally that’s when they would start medication. Normally my Doctor is there and he would discuss the results with me and an action plan but he wasn’t in the office at that time. Has anyone had a similar situation? Did medication truly help?
