Low immunity to Rubella

Imeylda
Im very stressed and cant get my mind out of it! I'm 8 weeks pregnant and my blood test result showing i'm low immuned to Rubella. Just now i got a phone call from mom saying that my sister caught the german measle with her! And the doctor told her she's having it since about 2 weeks already.. And that 2 weeks i've been with her as well. Im so worried i will get it any time now, what to do.. I've booked my next appoinment with Gp this Saturday, please pray for me and my unborn baby :( hope things are okay and that im not infected..
