First time TTC with no luck

Hey guys! My husband and I have been TTC for 4 months with no luck. 😔 we currently dont have kids. We've been having sex every other day for basically two weeks around ovulation time using the glow calendar. I've been thinking of going to a doctor to make sure everything is working right on my end, but don't know if I'm ahead of myself with that. It's very disheartening for us and we just want a different result. I know patience is important during the process but feel like we're doing things how we're supposed to. What suggestions/tips/advice do you have to offer? Thank you!!
