Am I having contractions??

Jacqueline
FTM- I'm 33 weeks pregnant, this is the second time I've had pain at the top of my stomach. It gets so tight it's hard to breathe. Are these Braxton hicks contractions? It went away after about 20 minutes but it's very uncomfortable. My husband thinks the baby was just really high making me uncomfortable until she moved to a difference position. Thought?
