Carrier Screening

Has anyone had their carrier screening tests? We just got the results back from mine, and apparently I'm a carrier for spinal muscular atrophy :/ my husband is getting tested on Monday to see if he is a carrier as well. I'm trying not to think about it, but I made the mistake of telling my mom who is absolutely stressing me out. I guess I'm just venting here because there's really nothing we can do until my husband's tests come back. I just want to enjoy being pregnant.
