2 week wait after IUI - day 15

I had my first <a href="https://glowing.com/glow-fertility-program">IUI</a> on September 28, my doc told me to test 16 days later - which is tomorrow (or technically today in about 6-7 hours). Obviously I'm very nervous though very certain that it didn't work this time. Had no symptoms, not feeling different in any way, and of course it would be too easy to work after the first <a href="https://glowing.com/glow-fertility-program">IUI</a>. I think I actually kind of gave up a little bit already :(
Trying for about two years now. Next week is my birthday, I'll be 34. We're both perfectly healthy, no issues all. Apparently just unlucky. :/
Anyway, just wanted to vent a bit because I already kind of know what the test is going to say and I really don't want to see it.
