I know I was the same it took me 3 days to come down from that high I was dancing around being silly I was just so delighted. When you have prepared for the worst and you get told the best it's amazing but also hard to believe. I had to try not to sob during my scan I was just so pleased she showed me the screen before she measured think she was also expecting the worst. I was destined to cry that day no matter what lol. Hopefully you can relax a bit now and start enjoying your pregnancy xx
