I am surprised that you could appreciate foetal hiccups.
As far as I know, the hiccups don't develop during the Intrauterine period. Apart from heart action and limb movements only breathing movements and some grimace of the face can be seen in Sonography.
But mothers are most welcome to give any description to any movement that they feel inside their Uterus.
