Baby hiccups in womb

Hi Mummies, is it normal for baby to have hiccups in the womb multiple times a day? I’m 31 weeks going on 32, and have been noticing baby is having hiccups quite often lately. I’ve read that you can switch position so that baby will move and lessen the hiccups, which worked for me as well. Just concerned she hiccups a few times daily, is it a sign of distress? I’ve read that it’s pretty normal actually if it doesn’t last more than 15mins per episode.
