@kymi91 I didn't have any notable Braxton hicks contractions before my daughter was born. It's normal to get them and also normal not to.
If youre getting them more often and they get stronger I would talk to your doctor, either call or ask at ypur next appointment. Its normal to have them this early, as long as they arent frequent and go away. They can be a sign of dehydration, so drink plenty of water and fluids!
Kymi91, not everyone gets them so don't worry!
What if you dont get them?? Im 23weeks & havent felt any..
Any time after twenty weeks as long as you get fewer than four to six in an hour.
