Baby movements in my butt 👣 ? 34+5 wks.

I feel a lot of reallllllly low movements. Like it literally feels like it’s in my butt. I still feel baby kicking my stomach & ribs & stuff.. but when he hiccups or makes (I’m guessing) head movements, I feel it superrrrrrr low. Like it feels like I’m about to 💩💨. Literally in my butt. He’s been hiccuping a lot more lately & I mostly feel it it in my butt. Sometimes I swear if I were to put my hand down there, I’d feel the movements 😂 Sorry idk how else to explain it. Is this normal???? 🥵
