77k MQMs earned
= 110k MQMs and $3200 MQDs
Have a trip next week that'll give me another 5500MQMs and $700 MQDs leaving less than 10k MQMs and $2500 MQDs before hitting Diamond.
Had I earned those 2000 miles last December, I'd have hit Platinum this past month, but no chance at Diamond.
Though I've had so many Monday or Friday travel days that I'm hardly ever getting FC with PM.

How are you calculating MQDs? DM requires $15,000 (or $250,000 spend on DL AmEx cards for the waiver). You say you have $3200 + $700 = $3900 counting next week's travel, so you need a lot more than $2500 MQDs for DM.
