Strange hiccup question

So I’m 35 weeks, baby is head down and they could feel her head when they checked my cervix at my appointment last week. I can normally feel hiccups in my lower stomach but today she has had them twice and I feel them so low it feels like I can feel them in my butt. She has dropped and I can feel them some in my stomach yet but has anyone else had this before? It’s strange and I feel silly asking🙈
