Risk of MMC?

Ca

Y'all I'm TERRIFIED of a MMC. I'm 12 weeks today and I don't have another doctors appointment till September 22 and a sonogram on Oct 6th. I keep reading that they're very rare but I'm still so scared. 😭 I still have my morning sickness, nausea, very light cramps, no bleeding.. I'm a FTM so I think everything scares me..
