I will ask my doctor at my next check up but it isn't until July so I thought I'd ask here first :)
I'm 32+5 and getting this really persistent pressure in my pubic bone, mainly when I stand up or sit down (any movement like that) when walking for too long (and I mean more than a couple of minutes) or if I try to run - it kind of feels like my fanny is going to fall out 
:o I wouldn't say it's really painful, but definitely uncomfortable and sort of like mild pain in that it makes me think ooh, maybe I shouldn't be doing that. I've stopped running or carrying my toddler unless I absolutely have to.
Don't have any discomfort in the bump itself. Is this just a normal part of later pregnancy? It didn't happen with my others but this is DC3 and my doctor last time said the pelvic floor pressure will get worse with each baby.
I googled it and it seemed to suggest PGP / SPD - but I always thought that was to do with your hips?? Have I just got that totally wrong?
