Any advice about these pains?

[Grumpy19]

Hi. I'm 24 weeks. This evening I started having quite bad period type cramps/ tensing in my bump and back ache.
It lasted about an hour and a half. It has now eased but I still feel a bit achy and tender from it.
Any ideas? I have a midwife appointment in the morning so I'll let her know.

@Grumpy19 sounds like your baby is lying in certain positions causing nerve pain/cramp ?

Oh ok. I hadn't thought of that as I always think of nerve pain as sharp (I get sciatica and this is nothing like that!)
This is DC4 and if I was 36 plus weeks I'd be convinced it was the start of labour.
