braxton hicks *can* hurt, even my doc told me that, its the fact that the uterus is contracting around the baby and it getting pushed against your cervix, it can easily hurt
they are most likely bh if they are irregular, if you havent yet try laying down, it can help a lot sometimes
but if you are conserned then deffinantly call your doctor, even if you think its stupid, call them, that is what they are there for, it may help ease your mind
