Kittycat : I am surprised your f/clinic, hasnt advised you that it is best to abstain from BD, for two days before IUI or IVF. You would be better to wait until after tommorows IUI, IMO, and when you get home, bd to your hearts content, that was our advice. I was worried that when I had the IUI they would know (ifnwim) that we had dtd, beforehand. My FS recommended to BD the night of, and the morning after IUI .. GL for tommorow
