I'm doing my first IUI this cycle. What should I expect? My RE's nurse just briefly talked to me about it on the phone today so I don't know much about it other than what I've read on here.

I'm taking femera, then doing opk's and am supposed to call when I get a positive (the last two month's I've gotten positives and confirmed ovulation with 7dpo progesterone tests, but BFNs). No other monitoring or trigger shots.

Is the IUI painful?
Should we still be doing timed intercourse EOD just to get more attempts on top of the IUI, or should DH be "saving" it for a better sample for the IUI?
Did your DH stay with you for the IUI or leave after he provided his sample?
