I know this is different for every body, but did you notice a bump lower, near the bladder area/lower abdomen or higher up in the stomach area?
First baby, 13w and don't really notice anything too different. I am an average build but you definitely couldn't tell I'm expecting. Kind of embarrassed to even ask this question (considering I'm almost 39).
Re: Initial weight gain - where can you see it?
It starts lower and grows up. Your uterus stays well behind your pubic bone until you’re in your second trimester. For a first baby it could be 16-18 weeks before you start noticeably showing.
