16 week baby bump

Brittany

so I'll be 16 weeks pregnant Friday and I don't know if I'm showing or if I'm just chubby. I weighed 245 when I first got pregnant and now I weigh about 215. it looks like I have a belly starting but like I said I was a bit chubby before getting pregnant but I'm not sure. when did you start showing? I'm a first time mom and IDK what to really expect when showing.
