Is it possible to develop a "bump" after only 5 wks and 5 days? My stomach is bloated (as are boobs) but my weight is the same. Obviously I know the baby is somewhere between sesame seed and apple pip but does everything inside swell up or do you retain water on your tummy in preparation? My diet hasnt really changed except no booze and I wasnt drinking much anyway. I know it sounds mad but I really do look like I have a small bump and am wondering if it might be a sign of twins or if anyone else has experienced this?
