With DD1 I was showing enough that people would comment by 5 months. Dd2 I was still having to tell people I was pregnant the week before I had her- never even got out of my size 8 skinny jeans. This time, DD3, I have been noticeably showing since 3 months. Now at 18 weeks I am bigger then I was when I gave birth to dd2. I'm already in maternity clothes.
