Overweight and Pregnant !

Im 5'11 and 259. I've been told I look less then I do because I carry it well but lately I've been carrying most my weight in my stomach. I'm 7 weeks and 4 days and I feel as if tho I'm getting a baby bump but not sure. Is there anyother tall/overweight moms that can tell me when they started showing ? Because Id love to have a real baby bump and not just a big fat belly. Pics included ! ​​​
