You can apply for the second FLR(M) shortly before the 30 month anniversary living in UK as spouse. Your initial visa was valid for 33 months, so the eligible period varies according to your arrival date and not to the Visa expiry date.
Technically you may submit FLR application anytime between then and visa expiry
