Is this Braxton Hicks

I’m 29 weeks and all day I’ve had lowe back ache that still hasnt gone

I’ve been having cramps the kind where you need to go for a poo

SO I did and whilst going my belly felt really tight, felt like I had a stitch from one side to the next and it was very painful when I loved like a shock feeling

It’s gone now

But my back ache is still there
