Increased hunger and ovulation

Anyone find themselves ravenous during their fertile window? I don't think I've ever noticed it before but I have been so hungry the last two days and I just started my fertile window with OPKs getting slowly darker but not positive yet.

I cannot say I've been craving anything in particular I just feel like I have been insatiable for two days straight. (Normally I have next to no appetite and consume about 1300-1500 call day).

Anyone else? I read some other forums and seems to be a trend for some moms. Anyone find they ovulate soon after this increase in appetite? I'm desperately hoping for earlier ovulation this cycle since we already BDed and can't do it anymore this round
