I was about 28wks when I started showing.
I'm 18 weeks I dont really even look preggo yet!
Im 16 weeks and im barely showing , I have a small bulge on my stomach and at different times in the day I get bigger and smaller lol.. I was told that it will probably be 20 weeks before I properly start to show! But everyone's body is different :)
Istarted showing till iwas 7 & a half months lol. Now im 8 & a half n iswear im huge now. Dont worry too much about it just make sure you exercise and eat healthy.
Yeah im 16 weeks pretty small sized and i woke up one day thinking i was bloated or constipsated lol but i pressed my tummy its hard. Everyone is different but i think we will just look bloated for a while i dont look like im showing just my belly pushed out a bit .
