I thought about it
Yes, I thought about it.
Dix mille fois j'y ai pensé, cette fois, je le fais.
I've thought about it ten thousand times; this time, I'm doing it.
— Les Ailes du désir (1987)
I thought about it really hard.
J'y ai pensé toute la journée.
I've been thinking about it all day.
J'y ai pensé la moitié de la nuit.
I thought about it half the night.
