we're moving forward with IUI to start

Sarah
My husband and I met with my OBGYN yesterday. She looked at his SA results and said we are going to need assistance with getting pregnant. She's hopeful that <a href="https://glowing.com/glow-fertility-program">IUI</a> will do the trick. She's ordered day 3 and day 21 blood work for me and a saline sonohystogram. He's doing a repeat SA and our referral has been sent to a fertility clinic. 
I've been going through such a roller coaster of emotions lately. I'm excited that we're moving forward, nervous about what to expect, and just overwhelmed I guess. I find myself crying at random times throughout the day, not really sad at all just really emotional! 
Anyone else find themselves feeling like this? Any tips or advice? 
Thanks!
