When did you start seeing your twin bumps?

Twins 💗
I am 10 weeks Thursday and although I am bloated I can feel my uterus low down in my abdomen. I have also lost 2lb since the beginning of my pregnancy due to nausea. But I can't hide the bump. Does anyone know how much bigger the uterus is with twins compared to a singleton pregnancy. This is also my third pregnancy so I expected to show slightly sooner anyway. Thanks.
