Ahh want to test but dont want to be disappointed

Stephanie • I have 2 amazing kids a girl whos 6 and a boy whos 5. They are my world. I had a terrible car accident in november when i was 14 weeks and lost my 3rd child with the man ive been with for 2 years now.
Af is due in 3 days, i have a test left but a part of me doesn't want to test and the other part does. What should I do
