Bluebird Jones,
With respect to Iain here - I recall that you applied for a fiance visa. In that case, you have just 6 months until it expires. If it is issued, say, on March 1st, then the visa will expire on September 1st, regardless of when your fiance comes to the UK. Also, bear in mind that in those 6 months, you have to get married, and apply for FLR (not sure when is the best time to apply, maybe 1 month before the visa ends), then you can see that it is a tight schedule.
