 So, the beginning of your pregnancy in the first trimester is when all of the ground work is laid, all of the organs are established. So now it's just growing and growing rapidly. So at this point in your pregnancy, your baby is probably around a pound. Under the ultrasound, you're seeing some movements and now it's really actually looking like a baby rather than a little peanut. So a woman tends to feel like now there's more evidence that she's pregnant so she can still feel that fullness and those around her can start to see that little baby bump form.
