Soph, I don't think for your first you are opopping late Lady at work whom is tall & due before me, probably same date as you & you cannot tell at all! I am short & have a big round belly this time & people think I am about to start maternity leave !!! I am not due til Sept! But with maddy I was in my usual clothes including jeans & smallish T-shirst showing a tight skinned belly, but not a round preg belly, just a firm one at 22 weeks & at 25 wks people finally started noticing!!! I think it's totally normal you are not popping late!!! I know it is all that my friend from work is waiting for, her usual clothes are too tight, but maternity clothes look like sacks on her! So she feels same as you!!!!
