In my first pg, I was bloated like a puffer fish (due to drugs, although I don't know if I was borderline over stimulated???) so at 12 weeks I looked like I was 20 weeks. I did 'pop' though around 18 weeks I think (ie the swelling from the drugs went down and my bump came out more firmer). In my second pg, I popped a lot sooner, I think around 14-15 weeks I think.
