Asking for prayers, positive vibes, etc

My husband and I have finally gotten pregnant through IVF. I will be 14 weeks this Friday. I got a call from my doctor today that I tested positive as a carrier for spinal muscular atrophy (SMA). Now my husband has to get tested to see if he is a carrier. If he’s not, we are safe. If he is, I’m scared of the next steps. I’ve been crying all day and thinking the absolute worst. Has anyone ever been through this?? I feel like we can’t catch a break 😕
