Fragile x syndrome

I don't know how many of you have a had blood work done to see if your little one is is at risk of any diseases but I got the verifi testing done through progenity and my doctor called me today to let me know that I am a carrier for fragile x syndrome, I don't know if any of you have had this but if so how did you go forth from there, I have 1 sweet healthy 3 year old boy already and he is no affected by this and is healthy and I know I have to go in for further testing now and that the baby I'm pregnant with right now may not have this but I just was curious how any of you have gone through this?
