Your body is just preparing it sounds like, but if makes you feel more comfortable, you can certainly ask for a sooner appt. Are you dilated at all or no? If not, then I wouldn't be too worried unless your contractions become very regular, in a pattern and more painful.
write them down, just in case. i didnt realise how frequent my contractions were until i noted them which were 3-4 mins apart and lasting 45 seconds. could be the final run down of your body preparing for delievery so i would wait until they get worse, you get back pain with them, your waters go, a show etc because having 2 signs of labour can not just be blamed on braxton hicks. if you did go to the hosp all they will do is see how far dilated you are and if it is very little they will send u home anyway but if you are concerned its better to be safe than sorry so i would ask. good luck!
