Munchkin: I think that could def be the plug. That's what mine looked like first time around. I never noticed it with ds2, and this time I think I'm losing it bits by bits, like 1 -2 mm in size.
And don't worry, we've been stalking each others for months now, we shared our wobbles, our happiness, we peed ourselves, pooed ourselves, so what's a pic of mucous plug, huh? ^^
