14 + 1 - belly popped??

Rachel • Expecting our first little one in June 2016...
For the last 3 days my clothes have been getting noticeably tighter, and I'm shocked to see that out of nowhere I seem to have 'popped' out a little bump? This early? Anyone else or could it be wind...?! I'm 5ft 3inches and been told shorter people show sooner? All new to me, this is my first pregnancy...
