I'm 15 weeks pregnant and my tummy already feels firmer but I just can't wait to have a proper bump! Does anybody have any idea when I'll start showing? This is my first baby and I know it's not something huge to be worried about but until the past year I've never gone above a size 12 so always presumed I'd had a nice round baby bump when I got pregnant, but now I'm slightly worried! Thank you in advance!
