You would see in the sky before dawn or before sunrise. The older the moon's phase gets, the lower it is in the sky.
(Restating the question as "What phase of the Moon follows 'waning gibbous'?) The phase of the Moon which follows 'Waning Gibbous' is 'Last Quarter'. The Gibbous phases are the periods when the Moon is more than 50% illuminated. Waxing being the period when it is approaching Full, and Waning being the period after Full, but before 'Last Quarter'. See Wikipedia entry for "Lunar Phase"
Crescent.
The New Moon, First Quarter, Full Moon, and Third Quarter are moments in time, with no duration. The Waxing and Waning Crescents, and the Waxing and Waning Gibbous phases, each last roughly a week.
Two weeks after the waning gibbous phase of the moon you will see a new moon.
Both of the waxing phases have more of the Moon illuminated each night:Waxing crescent - from 1% to 49% illuminated(first quarter)Waxing gibbous - from 51% to 99% illuminated.
You would have to wait until after the moon is full. Then, the moon is in its waning phase and you can see it!
1 or 2 days

In a typical month, you can see two crescent moons: one during the waxing phase and one during the waning phase. The waxing crescent appears shortly after the new moon, while the waning crescent appears just before the new moon again. Depending on the lunar cycle, there may be slight variations, but generally, two crescent moons are visible each month.
Crescent.
The New Moon, First Quarter, Full Moon, and Third Quarter are moments in time, with no duration. The Waxing and Waning Crescents, and the Waxing and Waning Gibbous phases, each last roughly a week.
A waning crescent phase typically lasts around 7-8 days until it transitions into the new moon phase. So, it will take about 28-30 days for a complete cycle from one waning crescent to the next waning crescent phase.
Crescent is the phase that's less than half. Gibbous is the phase that's more than half, but less than full.
Crescent, waning
Two weeks after the waning gibbous phase of the moon you will see a new moon.
The crescent phase.
The phases of the moon that we cannot see are the New Moon and the waning crescent phase, specifically when it is positioned between the Earth and the Sun. During the New Moon, the moon is illuminated by the sun on its far side, making it virtually invisible from Earth. Similarly, the waning crescent phase occurs just before the New Moon, when only a small sliver of the moon is visible, often making it difficult to see against the brightness of the sky.
