first trimester testing

So I had my second appointment last Friday. I had a culture done, blood drawn, and heard the babies heartbeat. I got the results back today and everything is normal except for rubella. I have to be careful not to be around sick children (but I'm teacher 😂🙈)! I go Wednesday for my first trimester genetic testing. Nervous but praying that everything is fine. Anyone else have experiences with either rubella numbers being concerning or genetic testing?
