Im 24 weeks pregnant and experience braxton hicks now at least twice a day, is this normal?

Yes: Braxton -hicks contractions usually start during later part of second trimester and cont until labor... Regular follow-up with your OB doc is recommended...

Maybe: It is not unusual to have occasional mild contractions, usually felt as a tightening of the abdomen. Generally if you are having less than 6 contractions an hour this is ok. I would suggest that if you notice your contractions increasing in frequency that you give your doctor's office a call.

Yes: You will continue to feel occassional contractions throughout pregnancy. A few per day is within normal limits. If they become regular or increase in intensity, go to the hospital. As long as the contractions are not contributing to cervical dilation, they are usually benign. Make sure you are staying hydrated as well.
