The road to fertility

Ellie
So tomorrow we are going to the hospital for an ultrasound transvaginal pelvis scan.
After consulting with the doctor and telling him that I do not ovulate, he looked at my blood test results and has sent me for an immediate referral to the fertility clinic. 
Has anyone else had this scan? If so, how did it go? What happens? How long do the results take?
Thanks girls, fretting about it all.
