Over a year and still not one positive

I’ve been ttc for a year now and I’m only 22 years old, starting to get worried, but every month I over think things and think the slightest thing is a pregnancy symptom. From really early on, for example today I’ve had really bad acid reflux and so I sit on google for about an hour searching for anything to even slightly prove that it’s a possible pregnancy symptom. Did anyone get any actual early pregnancy signs? and has anyone done anything to help boost fertility?
