Bump support band-which size?

[Em1503]

Hi, I've got a mamas and papas voucher and want to use it to buy a support band. Anybody bought one and know how they come up size wise? The small goes up to a size 10, whereas the next size is 10 upwards. I'm usually a size 10 so stick as to which one to buy?!

I got one from mother care I think it was the medium size but I tried it on in the shop before I bought it. It had a large velcro bit on the back so lots of easy adjustments as my bump got bigger.

If I were you I think id get the bigger one as if needed you could always make it smaller but you cant make it bigger and being pregnant youll only get bigger.
