Afraid of getting the flu jab while pregnant - did u have it and is your baby healthy?

I'm 30 weeks pregnant and have been asked by my obstitritian to get the flu vaccine but i've read so much negative things about the flu vaccine while you're pregnant and how it is linked to Autism etc I'm so afraid of getting the jab but i'm also so afraid of getting the flu and putting my babys health and wellbeing at risk. What do I do?
