So my question is with the halfing days away, will that effect how much a MN earns per day? Obviously it effectively halfs the block reward when mining but how if at all does it effect the nodes
Due to the halving, an MasterNode will only bring in half as much as before. It always depends on the block reward, how much you can earn with a MasterNode. 50% less block reward = 50% less MN reward. No other changes are expected as a result of the halving.

Don't you notice that you didn't get a reward for running masternode?
Yes, I've just read it in telegram some minutes ago. MN reward becomes active when the exchanges have updated. So it's gonna be a few more days before you get a MN reward.
