My husband and I took our ovidrel shot Friday around 6 and we're scheduled for our IUI on Sunday. Everything that I've read thus far says there is between a 24 to 36 hour turnaround for ovulation. This is our 3rd round of clomid but first IUI. The rounds before that were timed intercourse. Does anyone have any experience as to how long it takes from ovidrel shot to ovulation to IUI?
