Не рано совсем. С 6 нед. они идут, просто не чувтсвуются так рано:"Braxton Hicks contractions are sporadic uterine contractions that start about 6 weeks into your pregnancy, although you won't be able to feel them that early. You probably won't start to notice them until sometime after mid-pregnancy, if you notice them at all. (Some women don't.)" http://www.babycenter.com/0_braxton-hicks-contractions_156.bc
