Bumpin - when did you start showing?

Kira
I'm 12 weeks and 2 days and feel like I'm at that weird quasi "chubby" stage. Anyone else?! An avid triathlete and marathoner (prior to prego of course) I haven't been able to do much of anything since I've been so sick. The last 1.5 weeks I've been on medicine and now feel even chubbier being able to keep food down lol. Now I need to start exercising ! I would rather just show already vs stuck in the weird stage haha! 
When did you start to "pop"??!!
Ps I should also mention I'm pregnant with twins!
