I'm 27 weeks pregnant and a couple of times over the last 5 days or so, I've felt (in addition to usual movements) and weird rhythmic movement quite low in my belly, It usually lasts no more than 10mins. It feels almost like a heartbeat but it's way too slow to be the baby's and I imagine I'd never be able to feel that anyway. Is this the hiccoughs people talk about, or am I having a dancer or musician who only moves precisely to a beat?!
