Bump at 12 weeks

So I’m a little over 12 weeks and already am showing. You know how they say you show earlier with your second? Well does that apply to only LIVE births or to pregnancies even if you’ve had miscarriages? This is my third pregnancy but the furthest I’ve ever gotten. Just curious if that’s why I seem to be showing so soon as I already had some bloat at 8 weeks. And am in maternity clothes already. Thanks!
