With this pregnancy, I am 13 weeks, and already showing. With my first, I didn't show until 20 weeks.
With my first I was about 5 months before I started showing, that is about 20 wks. My second and third before I was 4 months. They say with each pregnancy it's different but after the first it's usually early. Make sure you post pictures when it starts to happen. It's a good way to keep track of your babies growth. Especially if this is your first, it's nice to look back on.
I had a bump around 8 or 9 weeks. I think alot depends on how you carry. My little man is right out in front like a little beachball. Now, when I say I showed at 8-9 weeks, I could tell and DH could, but I am not sure anyone else could. Others really began to notice around 13 or 14 weeks.
I "show" very quickly. By the time I'm 8 weks I have a swollen belly! & FOR SURE by 10 weeks it's there!
But I think most people who didn't really know me wouldn't notice til around 12 weeks.
I was begining to show around 11 or 12 weeks..a little bit of a belly..to the normal naked eye (anyone else but myself or husband) Im sure no one could tell...but to us we could see a bit of a change..
But by week 14-ish there was defin a little bump going on..and now nearing my 20th week..You can defin see there is a belly going on there...I think it depends on your body type and defin if you have had babies before..
I'm showing now and the top of my uterus is already at my navel (which is more like 18 weeks than 15 I was told!), but in clothes I just look fat.
