What is this??

I'm 29+4 now and sometimes I feel a pulsating rhythmic beat in my lower belly. At my 28 weeks scan doctor said the baby is head down. I've googled it and found out it might be hiccups, but they are certainly more frequent than an adult's hiccups! It is impossible to just be kicks, it's too rhythmic and too frequent! Sometimes among them I feel real movement. What could it be?
