I see. Well either way it sounds like you had good timing and if you follow it up with a lot of BDing then you've covered all your bases! I think you have got a good shot this cycle.
I am nervous about my timing this cycle too. I usually go in for an ultrasound on cd12, get an ovidrel shot that day, and then go back on cd13 for the IUI. This cycle they are having me go in on CD10 for the ultrasound since I did my blood work two days early and started taking my meds one day early. Nothing wrong with doing the ultrasound early... I am just hoping they don't trigger me too early because I am hoping to grow more than one mature follicle, which might take more time. I think if it is too early, they will send me home with the trigger shot and ask me to do it myself within the next couple days. I guess I have to trust them, but it's so hard. I don't know why I doubt these doctors so much! I guess because I feel more invested in making this work than they do. Not that they have given me that impression, but sometimes I wonder what the incentive is for them to get us pregnant quicker? I guess so they will be able to publish good success rates, but I can't help but think they could make a whole lot more money if it took longer. I know I am being cynical but I just wonder about this stuff.
