Braxton hicks just feels like a tightening sensation where ur tummy gets hard. It goes away after 20 or 30 secs and comes and goes at random times. It does not hurt, but may feel a lil uncomfortable depending on ur position if ur sitting or laying down. They r nothing like true labor contractions.
Ur belly will gets so hard,then u will probably sweat a little and feel a little dizzy too.
They feel like regular contractions but won't progressively worse or closer together. On top of that, they should stop if you lay down or change positions.
