Rubella vaccination

So fiance and i have been ttc for 6 mths. I found out Dec 12 that my rubella level was 0 😐 had the vaccination on the same day (12th) and now waiting til feb to have my levels checked (have been told by health nurse that 28 days is the norm to wait) again...im 34 in feb and feel time is ticking 😢😢 has any of you lovely ladies had a similar situation? Did you ask for an earlier blood test?
