I am 11 weeks and some change and have been having a fluttering (more a vibration like a phone vibrating) sensation in my lower uterus and cervix for the past few days. It comes and goes, lasts a few seconds then recedes. It is not painful and if I weren't so early, I would swear it is the butterflies of the baby first movements.
Has anyone else felt this before? Does anyone know what it is?
