At what stage during pregnancy did you start to feel pain where baby was sat on a nerve, sending pain down your leg/bum?

At least I think that’s what it is. 🤷🏼‍♀️

I remember this feeling with my Son, suddenly my leg would just go or I couldn’t put any weight on it!

I am currently 20w5d and tonight I’ve got a lingering pain going right from my bum into my thigh.

It’s a constant pain; almost like you can feel where it’s shooting down.

I don’t remember when it started with my Son?

Just wondering if anyone else is experiencing this and has any tips for easing it quickly!
