I need some words of wisdom

My husband and I are having no luck at getting pregnant. I'm feeling a bit frustrated..trying to remind myself everything happens for a reason. I've taken pre natals, eaten healthier, used Pre Seed, OPKS, <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation apps</a>, etc. and still no luck... I just need some over all advice or tips. I'm feeling very discouraged. I'm 22 and my husband is 25. I guess I wasn't prepared for it to take a long time for a young healthy couple. Please leave POSITIVE thoughts below..
