Hello, We are ttc. On day 15 of my follicle monitoring, the dominant follicle size was 11 *11. An ultrasound on day 17 showed rupture of this follicle with mild free fluid. Does this indicate ovulation? If yes, then would have the ovulation occurred? Is ovulation possible with 11 mm dimension? My cycles are regular and are of 26-27 days. With this cycle length, is ovulation on 17 day healthy? Regards, Rekha
