What is "heqet"

To the Egyptians, the frog was a symbol of life and fertility, since millions of them were born after the annual inundation of the Nile, which brought fertility to the otherwise barren lands. Consequently, in Egyptian mythology, there began to be a frog- goddess, who represented fertility, referred to by Egyptologists as Heqet (also Heqat, Hekit, Heket etc., more rarely Hegit, Heget etc.), written with the determinative frog.
