Am I feeling hiccups??

I'm 19 weeks tomorrow and for about a minute and a half just before I could feel like a slow, pulse like feeling in my lower tummy. I thought it was movement at first but it just kept happening and was like in time with a beat or something lol. Just one pulse every few seconds or so. Was so strange, but google says that's hiccups? Is it normal to feel them this early? Or is it something else?
