Wind pain OR Something Else In pregnancy?

Jess • Been with the love of my love for almost 8 years, married 17/08/19 baby boy 💙 👶 05/10/2019 baby boy 💙👶 April 2022 baby girl 🩷🧒 March 2024

I’m 33 weeks 3 days all day I’ve had wind pain well I think it’s wind pain, I’ve been having pain it feels like I’ve got a stitch. I only notice it when sitting down I’m fine standing, I have been burping a lot. Also my baby has dropped & is head down can that be uncomfortable? I’ve noticed since his changed positions I have been feeling uncomfortable sometimes. Any advice would be greatly appreciated for this first time mum.
