Thats normal! It is currently taking anywhere from 9-12 months for initial reviews lately. You just email the embassy asking for the file number just make sure to include, applicant's and sponsor's Full Names, Date of Births, Client ID, addressess and contact numbers and hope you receive your file number soon via email. Its better to quote the immigration file numbers on the documents you are sending as it makes it easier for them to attach documents to the appropriate file and less confusing for them. CAIPS are useless as of now, you won't see anything until they do your initial review so wait for the first request and then apply for CAIPS that way you would know what they think of your marriage.
