Hi Daisy,

I had the exact same thing around that stage. I came home from the shops one morning and started freaking out thinking something was going wrong. So i called my sister who has had 3 kids and she said she had the exact same with all 3. As hard as it is to imaging, its just your uteris growing, as it grows before the baby grows and all your other insides are making room.
As you say, there was no bleeding detected in your scan so by the sounds of everything you are experiencing is normal.

Dont say it doesnt look good for you, keep positive girl! Youll be right!
