IUI #1

Tomorrow morning I go in for my first IUI. I'm a little nervous and a little confused. I picked up my injection of Ovidrel which they told me to bring with me however, everything I have read states you need to take it 12-36 hours before you are inseminated. I'm trying to let go of that obsessive thought and move on. Also, it says if you have a thyroid condition you should consult Dr/Phx. Ugh!! So I've said my prayers and just have to let go and let God and hope for the best.
