Contractions or indigestion

St

29 weeks with a crampy belly...Its happening every few minutes but they are not severe,just noticeable and slightly uncomfortable. The cramps are at the top of my belly and I feel a bit gassy/nauseated but am only burping a little bit...Do you think indigestion or possible contractions? Ive had Braxton hicks and this feels nothing like it🤔🤔🤔
