I didnt start showing til around 23 weeks.... but im thick tho. In fact i didnt even know i was prego til i hit the 23 weeks mark n took a 3 pregnant test. When i took it i thought i was only 2 months bc i wasnt showing... not until my ultrasound did i find ouy i was 23 weeks and i was having a girl :)
Trust me, you notice but nobody else will until you point it out :)
I started to feel chubbier that early. Sometimes just knowing something is going on in there can trick you though..
Not really if you were little then it will take longer for you to show. You really don't show at 7 weeks unless this is a previous pregnancy or you weren't small in the stomach area.
