I've lost hope with TTC 😞

TTC now for count em 5 years... No luck. I'm 27, he's 30. Neither one of has a child so we don't know who is infertile. I have ovulation pain, and very long cycles (30-40 days!) Well... I've lost hope and really depressed. Hoping someone can cheer me up. Lol. Or maybe have a similar story so I know I'm not alone.
