Ah ok - yep you won't see that.
You'll just have to wait for it to confirm.
However you can work out what your reward might be:

First consider how much you'd expect to get in 3 days of mining = T = 3 times the daily expected reward for your hash rate
Then work out how much of the last 18 says you mined = D
Your reward would, very roughly, be around T * D / 18

Now if you only mined with a tiny miner or D is very small, then you probably mined dust (dust is anything less than 10000 sat)
