Undergoing first round of IUI this week, any tips on what to expect?

Danielle • Canadian. Married. Registered Nurse. TTC x 3 years. 2 negative IUI :(
Hi everyone,
I'm 30 years old and my husband is 37. We have been TTC x 3 years with no luck. My fertility specialist has said that our infertility is more due to my husbands sperm. I have mild hypothyroidism and have been taking Synthroid for approx. 6 months now. I work as a RN in the hospital setting.
I guess I'm just looking for what to expect with the IUI process. I was taking the birth control pill continuously x 2 months and it was terrible - weight gain, migraines, emotional ++.  I have a history of migraines in the past and these were pretty terrible. It doesn't help that I cannot take imitrex or any NSAIDS. 
I go tomorrow morning for my ultrasound and start serophene. The other medications I have been prescribed include - prometrium, ovidrel, and estrace. I see  large list of potential side effects - anyone out there care to share? 
I'm pretty nervous and I just am afraid to get my hopes up. How many cycles does the average person have before it takes?
I'd love to hear any stories if anyone is willing to share. Much appreciated. God bless.
And I'm not sure why but it won't let me delete the word NSAIDS below lol.
Thanks! Xo
