Hello doctors I had done my follicular scan today which is day 5 and it showed two dominant follicles of size 13 mm and 16 mm on right side with ET of 4.5 mm. Planning for iui and doctor asked to get scan done on day 9 and trigger injection would be given once it reach 20mm . Is day 10 ovulation normal or is it too early? The follicle size seems bigger this time from my last period scan which is around 9 mm on day 5. Was treated for 4 days with fsh/LH injection 150 iu for 4 days. Kindly let me know if the size of fine for day 5 and is iui recommended ? Will both follicles rupture as both are above 10 mm?
