CONGRATS! How exciting!
I was in maternity clothes as soon as I figured out I was pregnant... I was running and dieting and had a flat tummy but couldn't figure out why my jeans were getting tighter and my hips wider... though, I didn't figure it out until I was about 6 weeks... this was me at 7 weeks. There was definitely no keeping it a secret and we wanted to wait until the 2nd trimester because of all our previous miscarriages! No secret there, sigh...
