Catch 22

Claire
So I feel I'm at a catch 22.... 
I have my long awaited first scan tomorrow at midday. 
My partner has come home early from work feeling horrendously sick. 
If I delay scan then it could be a few more weeks and I would like the Down's syndrome test which I am afraid he will miss.
But then he wouldn't be able to go if he becomes worse. Obviously do not want to go along and for him to miss this moment. 
I have a nervous tummy now as I'm worried. 😩
