Hi Maggie,

the same thing used to happen to me, i used to wake up and have no belly at all, i used to get up and think "maybe im not pregnant and ive just imagined the whole thing" but by the end of the day surely enough it would pop out and then after i ate dinner it would pop out even more and then there was no mistaking.

I wouldnt worry about it. soon you will be waking up in the morning and needing assistance to get out of bed like me because you belly is too big!!
