Idk keep tring or give up

I dont even know how to feel about it we been ttc for 7 months n nothing still. My cycles usto be 28 then 32 now 30, is my body stress or irregular if so its not helping me. Or maybe we are just not having enough bd. Theirs times i feel like giving up n just let it be but then again i want to keep tring or hoping for it. Idnt even kno how the husband feels since he doesnt talk about it at all.
