Is my baby autistic ?

Hager
So I'm 5 months pregnant it's my first time and I am very concerned I have two autisitc brothers and I'm just really scared my baby might be too . My doctor told me it's genetics none of the blood work or any exams I'll have will show if the baby has the chance to be autistic or not . If anybody is in a similar sititution or just some advice would be nice
