Can't predict: The 1 cm follicle you see now may not necessarily become the dominant follicle. There's probably a higher than average chance for it to; but it's not a given. The timing is usually a retrospective marker (e.g. tracked backwards) in the absence of biochemical confirmation. So, predictably, ovulation occurs about 14 days before onset of menses. So, in your case, that would be about Day #21.
