Help!!!!!!

Been TTC for 14 months now. 2 failed timed intercourses and 2 failed IUIs. I am in my 2ww after my 3rd <a href="https://glowing.com/glow-fertility-program">IUI</a>. How do you keep a positive outlook during your 2ww and keep yourself from stressing and obsessively searching for pregnancy symptoms? I get so disappointed because i dont notice any symptoms yet, and i dont feel any different even though it still is kind of early. I feel like i am going crazy and still have one more week before the beta test. Ughhh.
