My physician had me come back about 36 post hcg injection for iui. I was told 24-48 hr after injection u should have iui. Mine was on Easter sunday. Like you.....the tww *****!!!!!!! Best of luck to you! !
I know that I was doing the same thing but with timed intercourse... I was taking the hcg shot and then 24 hours later having sex. We didn't conceive during those six months, but my re is one of the best in the country and she assured me that the timing was absolutely right. I think it is all of the discretion of the doctor and how many mature follicles you have... I think that it takes a good 10 to 12 hours for the sperm to reach its destination so I think with 7 mature follies you probably have a good chance =) Best of luck to you!
