Congrats on good scan news Aoife & Bod!
I think I have a Middleton bump (yay! I'm posh!), 27wks & it hasn't come up anywhere near my ribs (had wicked rib pains with DS, nothing so far with this one), carrying very low (which would explain lower back pain & quite intense Braxton hicks right?)
Hope everyone cramping & brown bleeding is able to relax soon.
DH pointed out to me earlier that I had massive, top needed changing, boob leaks so it's full time breast pads for me.
