I swear it feels like baby boy is just a couple inches below my ribs, which is odd cause I'm only 21+4 but this has been happening since the near end of 20 weeks, I get this pressure up there by my ribs, it feels like something is there putting pressure on them, but no quite big enough to actually reach them. I feel him kicking and hitting well over 1 1/2 inches above my belly button & at the same time feel movement in my lower abdomen. can he really be that big already!?
