HI!
If you were my patient, I would probably tease you a bit about your question. First, I am assuming that you mean pounds and not years as I thought when I first looked at this. Second, there would be a lot of difference depending on height--if you were 5'0 or 6'0. An honest answer would be that most average woman "pop out" when they are about 16-20 weeks along.
LOTS of variables though!
Good luck!

That's a hard question, everyone is different and show at different times no matter what they weigh
I was 128 lbs and 5' 3 " pre-pregnancy and I didn't start showing til after 20-25 weeks and even then it depended on what I wore. I got so frustrated with people telling me I didn't look pregnant..
I was 123 pounds and 5'5 (ish) pre pregnancy. started showing at about 13 weeks. I don't know why you are so keen to show? I don't hate it, but i'd rather avoid my clothes not fitting anymore and everyone going on about how fat and gross I am now. It only matters that you know your pregnant and baby is healthy!
