Should I be worried?

Hi, I feel very weird posting. This will be my first time.

I’ve been in a very serious relationship since I was 15 (26 years old now) and we just got married in January! Yay! 🥰

We have not used condom or BC for the past few years and just used the “Rhythm” method to prevent pregnancy. I track my period very closely and I usually know when I’m ovulating so we had a pretty good system for preventing pregnancy. There were a few times that we were not so careful but I never worried about it then. We both wanted to wait until we were married to start a family.

Anyways, since our honeymoon we have been “unofficially” trying to conceive, we just thought we would have fun and enjoy it, but I’m starting to get worried. We have had sex during ovulation every month for the past three months and no baby yet🙁. I never thought infertility would be an issue, but here I am now worried. Should I be? Or should I just keep trying? Help!
