It took us 4 weeks back in november to obtain our fiancée visa and like u i was getting anxious so sent an e mail to "
ukinthephilippines@fco.gov.uk" asking why it was taking so long. I didnt get an acknowledgement but the visa was issued within a few days of receipt of my mail so u may want to do the same thing, at least then u know they might investigate in case its been overlooked in a pile of paperwork.
Anyway best wishes and be positive, the wait will be worth it.
