If the Graff follicle has grown to 30 mm, can I no longer count on ovulation in this cycle?

The Graafian follicle is a creation that, bursting, releases an egg cell - this is the moment of ovulation, i.e. the release of the egg. It may happen that the follicle does not burst, but constantly grows and eventually transforms into a functional cyst that should be absorbed - sometimes only in subsequent cycles. The absence of follicle rupture means that the female egg cannot be released. The next follicle should begin to grow in the next cycle, creating a chance for proper ovulation. I can provide you with such information from a pharmaceutical point of view, but the gynecologist who examined you is entitled to give an unambiguous answer to the question about ovulation in this particular cycle. Sometimes two Graff follicles mature - simultaneously in the same ovary or in parallel in two.
