Hiccups maybe?

I'm a FTM and 33 weeks so I'm not sure if this is normal? Around 3am it felt like my boy was having hiccups for about 10 minutes. He was kinda tensing/jumping it felt like every few seconds for like 5-10 minutes. It just happened again for about 5 minutes. Is that weird for him to do this? WEird that he is getting hiccups 2 times in one day? Has this happened to anyone else??
