So round so soon?

Miss • 🎃 Pumpkin due 10/12/18

So my boyfriend and I found out on 02/14 that I am pregnant 🎉 But it feels like overnight I developed this rounded out belly! I'm scared that I'm to big for being 6 weeks? I know it sounds silly...But is there any ladies who are showing already? Is this normal this quickly? I'm just in shock that I'm this round at only 6 weeks! I was going to try and hold off telling everyone for another couple weeks, but I don't think that'll be possible at this rate! Any advice or words of comfort?
