If you bled your brakes, then you might have air bubbles. Bleed again.
I pumped the brakes for about 5 minutes before actually hitting the road, the first time turning the car on led to the pedal sinking as well but then turned back to normal. I didn't bleed my brakes but I feel like I might need to if this problem persists
