Pregnancy advice ?!?!

If anyone has any advice or tips for getting pregnant or your stories of success or hard times! Anything would help! I’ve been trying to get for a while now and I’m feeling discouraged! I’m 21 years old and I’m married! And have had sex with my husband since the day we met and it’s been 2 years now! He does have a job that requires him to travel a lot so I’m not sure if our days are just not lining up with my fertile window or ovulation day which could be the case ..but there’s been times I know we had sex at least once in those days! So just anything you guys could tell me would be amazing and uplifting. Thankyou! ❤️❤️
