I don't know what the abbreviation BD stands for but if it has to do with having normal conventional intercourse the answer is yes, we did it both before and after. I don't think it worked as I'm starting to feel premenstrual now but have decided to switch to a new doctor starting next month. This RE was not very friendly and insistent that I should do an IVF even though I made it very clear that I do not want to go that route. Hopefully the new doctor will work out better. Thanks for your feedback.
I would say YES they are waiting too long! The egg DOES live fro 12-24 hours after it is released, but it's much better if they can do the IUI just before O takes place, cuz sperm can live for up to 5-7 days!!!
Some RE's do 2 IUI's one just before, then a 2nd 24 hours after, & thats OK I guess, but I think I would rather save my $ & BD the day after.
Did you guys BD a few days before you O'd?
good luck!
