That's a great size. My doctor likes them between 20-25 mm. Good Luck!Thanks hopeful, yes that's helpful. I actually saw one egg before I got pregnant with it, no meds (which turned out to be my 2nd miscarriage) it was 21mm and still 36 hours away from release! I often thought that was too big/overripe - do you know anything about what size they're supposed to be?
