First of all thank you to everyone who is devoting their time on this forum and helping people like me. I am quite active on tripadvisor myself

I and my husband would like to apply for British citizenship. We are originally from Poland. We did not apply for ILR, PR etc. Here is our situation:
Husband
started working in the UK on 22/05/2007
has a WRS certificate (both parts) dated 25/06/2007
he has continuously worked for the same employer until present and has all p60s
I
arrived in the UK June 2007 and was looking for a job
started working on 17/09/2007
have a WRS certificate issued on 29/11/2007 (but one of the parts states that I have been employed since 17/09/2007).
I have worked for the same employer until present and have all p60s.
We were not married when we first arrived in the UK and got married here in December 2009.
I know that to be on the safe side we should apply after 29/11/2013. However, could we apply after 17/09/2013 which is 6 years after I started working (and WRS although issued 2 months later confirms that date)?
You are probably wondering why is it a problem for me to wait extra two months. We are expecting a baby in November

Thank you!
