Heartburn or acid reflux?

Not sure what im having.. im thinking heartburn. I have never had it before but started getting it about 3 months ago. Only a few times a month nd never with the same foods.. i eat alot of the same stuff but have only experienced it with different foods. I know im not pregnant so that cant be the cause. Im 24 and never experienced this this til about 3 months like i said.. has anyone ever had this issue and what have u done to help it.. ive tried drinking water and it makes it worse.. Actually any fluids i drink seem to make it worse milk water orange juice just anything in general.. i was up all night with a burning sensation in my chest.. im thinking of going to the dr but not sure what to ask for so any advice would help.. thank u
