I dont understand

I'm so over , trying to get pregnant and trying to conceive. I feel like iam stressed out trying to find that peace in me . So I can have a baby. Me and my boyfriend have been together for almost a year and still nothing. I've tried fertility pills and a specialist telling me and my boyfriend we are good. I've tried laying flat on my back with my legs up , going through books on when to conceive and apps . I dont know what to do I feel like giving up, yeah I'm over weight a little but I feel like I just let down my man for not giving him a child. I'm giving up, I dont know what else to do.
