I'll be 12 weeks this week and there is definitely a little popping occurring but I've been super sick and my uterus is inverted which means I've shown late in all prev pregnancies
It's just a matter of how your body works, every person and every pregnancy is different. I didn't have a bump until 6 months and now I'm 7 and it's still tiny but I know people who started showing at 2-3 months. It all depends on your body.
