How old is your JRT? You should not be breeding her on her lst heat. At least her 2 or preferably 3rd.
Is she registered?
Do you have a registered male?
Have you BAER tested her and the male? That is for deafness, which is known in the breed.
Have you CERF tested both That is for eyes, very well known problem in the breed.
Do you have homes for these pups at 8 weeks?
Are you ready financially for that emergency on a holiday weekend? C-section / sick puppy / etc?
You should find a mentor to do this and a good vet.
