30 and trying

So I recently turned 30 years old and my husband and I have tried for a year with no luck. I'm trying not to stress about it and overthink but I can't help it. I want to be a mom so bad. I tracked my ovulation for the past 5 months and we had sex on the days that I was ovulating (good sign, right?) but still nothing. Please tell me this is normal? I can't help but think something is wrong with me because I am not getting pregnant the first time. My husband and I are going to the doctor soon to check both of our ability to even be able to get pregnant. I hope all will be okay from this appointment. Please pray for me!
