Baby causing hiccups??

I'm 14 weeks tomorrow and ALL day long I'll get the hiccups. Now it's not like your normal hiccups, it's just one at a time. During my ultrasound yesterday, he/she was moving around and even looked like waving at us and at that exact moment I hiccuped like I have been. Since I can't feel her yet I'm now guessing my hiccups are caused by her moving around?? Anyone else had these random yet constant hiccups and what was your assumption for it????
