Shelly I would say thats what it is. You will probably start getting short of breath now too as you will experience everything quite a bit earlier than the rest of us. My MIL was a nurse and she likes to let me know what symptoms I have to look forward too!
Anyway, heres the wee bump in the afternoon. (I want all of yours after this) I read somewhere that in the mornings our spines are stretched out more so we are all an inch taller or something. Maybe thats why it grows during the day? Either that or pregnancy comes with a tonne of gas!! lol
