Sounds like your dates are out. Our bodies do strange things and you've had that issue in the past.

I would just keep thinking, there is a sack, a blob, maybe not as big as you'd liked it to be, but it's there!

You can't worry about things that are out of your control. Just keep thinking happy thoughts and picture the baby in your mind with a beating heart, and you'll see that on the 24th!

Take care really try and relax, spend time with your family and friends to try and take your mind off it, and time will go quicker. Trust me, it's working for me and I don't have my next scan until the 30th, you you're before me!!

Let us know how you go.
