Where do they usually find baby’s heartbeat ?

If you ladies have NST’s or even at your doctors appointment, where is baby’s heartbeat usually found? Baby was breech until 33 weeks, after she flipped her heartbeat was always found below or at belly button level. Today at my NST her heartbeat was 2-3 above belly button level. Hoping she’s not breech again. 😭
