First IUI this cycle

I'm really excited but also nervous. I've done 5 cycles with just Femara, pregnyl trigger shot and timed intercourse. My doctor told me we could add IUI whenever I was ready after cycle 3. So I made that decision today. I'm taking 10mg of Femara CDs 3-7 and will have my ultrasound on cd 13 which will be September 9th. Then they will check my follicles and decide if the IUI will be feasible this cycle and tell me what time to do the trigger shot. Any words of advice or stories anyone would like to share? Would love to hear from others!
