I am on cycle day 12 and went for my bloodwork and ultrasound. My ultrasound showed a dominant follicle in the left measuring 24mm and my bloodwork was showing I was going to ovulate soon. My doctor instructed me to trigger. Is a 24 mm follicle pre-trigger too large/overripe? Does the follicle grow much after the trigger. We are thinking of having timed intercourse tonight but I feel hopeless thinking this is too big.
