Baby position

I am 36 weeks and I know they will start checking the baby’s position at my appointment this week, but I have been trying to figure it out myself. I feel hiccups low on my right side usually, but often my stomach bulges on both the right and the left side when the baby moves and it’s higher than where I feel hiccups so I don’t think it’s the baby’s head. It can be uncomfortable/ a little painful at times so I was just wondering if any others out there have experienced this! TIA!!
