It could be that your baby is sitting to the back of your uterus and not the front.
I agree as well. I didn't start to really show until 7 months, and even then I could always easily hide I was pregnant. If this is your first baby it might take much longer than it would later pregnancies. This is just because the muscles are tighter than they would be later on. Never compare yourself to others. When and how you show is unique to you and your pregnancy alone.
Totally agree with the other three ladies, it's completely normal. Especially if it's your first baby...your stomach muscles are going to be stronger and it will take longer for you to show, on average. Most women show between 13-22 weeks, some later, but you should begin to get a little bump in the next month or two :-)
I agree, everyone shows at different times, I didn't begin to show until about 15 weeks, but I know others who didn't show until 20 weeks, some even later than that.
I started showing a bit around 14 weeks but really didnt get noticable until after 16 weeks and was still really small then.... and even then depending on what I wear, I can still hide it.. and im 20 weeks now but my belly looks quite ridiculously round bare... ..
I am like a size 0 so very slim to start..
i met girl who is 3 1/2 months pregnant with twins and she makes me look so small now.. i tell myself she has two but i am a month and a half around her.. i go for my ultrasound tomorrow so i hope everything is measuring fine.. but i have been growing significantly since 16 weeks and my baby is kicking all the times yet so i believe its growing.
You have to remember that everyone is different . So even though your not showing yet you will soon :)
