I had a follicular ultrasound on day 9 measuring 10mm & only one dominant follicle. I was given 75iu to wake up the follicles. I am wondering if I have a natural LH surge on day 11 that when I have a IUI on day 12 that the follicle will be big enough to get pregnant?
Hi actually your follicles don't grow that fast. It grows at a rate of 1 to 2 mm per day, and it requires a follicle of more than 17 mm to get a LH surge. It will require at least 5 to 7 days to happen from the size of 10 mm that means around day 14 to 16. You can also take an injection for LH surge when follicles become that big. Then you can have GUI the day after it.
