39 weeks! Help me!

An
My baby has been head down since 32 weeks. My doctor would check every appointment. My baby's hiccups would confirm. This morning I wake up and I feel hiccups on my right side almost level with my belly button or a little higher. This seems abnormal to me as I always feel them way lower. He was in the transverse position up until 32 weeks, is it possible that he changed position at 39 weeks? I'm worrying myself to death. I see the doctor in about 3 hours but I am just wondering what you ladies think?
