This is my First IUI cycle and I'm currently taking 100mg of clomid for 7 days.  Today is my last dose and I go in on Friday for my CD12 U/S and BW.  I know everyone is different but I'm curious on which day you did your trigger shot?

It will depend on how big your follicles are.. Sometimes if they are under a specific size then the dr will wait or aleast mine did because you don't want to waste a trigger... But they could administer it the day you go in for your ultrasound or a few days after.. Really just depends how well you respond to clomid. What dose of clomid are you on?
