Hi
It's usually about 36 hours, thats why they will have you booked in for egg retrival 36 hours later (if this is what your having done), well good luck anyways stay positive and happy!! xxx
i had my trigger today at 9am.
she siad you typically o - 36 hrs later.
My RE does IUI 24 hrs after trigger to be sure the sperm are waiting on the egg (incase you o b4 36 hrs). So i have my IUI at 10 am tomorow :)
I tend to O 48-50 hours after a trigger. It has happened the last two times - might be because I am carrying a few (HA! A lot!) of extra pounds. I dunno - just my theory...
