I am a little overweight and 16 weeks pregnant, when will i show?

I am about 5'3" and the last time I went to the dr. i weight 182 lbs. (ive actually lost about 8 lbs. during this pregnancy). This is my 2nd pregnancy (first one ended in a stillbirth) and I just wanted to know when abouts i will start to show. im getting a little anxious. thanks in advance!
