Of course you hope everything is fine, as do we all!
But, can you get yourself into a headspace where you can try and feel that it is what it is? I'm not great with the words I want to use, but can you see that the days you spend, sick with anxiety, are days wasted to you? They won't affect the outcome of Monday.
Everything crossed, and statistics good, all will be well! So you worried yourself anyway. God forbid a less happy scan- what will you get out of feeling your fear was justified? All it will do is emotionally blight further early pregnancies.
I used to spend literally hours willing my plane to stay in the sky. It can almost become a fetish. Til, not overnight, but gradually I came to realise that my tight knuckled prayers and chanting actually made not a ripple on the fabric of the universe.
What will be, will be. But it took me to 50 to realise that.
Hoping all goes well!
