Keep waking up early for no reason

Im 16 and i thought my sleep was gonna be perfect because im young but like i dont understand whats wrong with my body. Sure at night its fine, i am always able to sleep at 10 pm perhaps 10:30 easily and thats what i always do, but then i would wake up at around 5 in the morning sometimes a bit earlier to go pee. And afterwards, im unable to sleep again.

This all happen after a trip so i thought it might because of jet lag but its been a week by now and im not sure if jet lag plays a big role here. Regardless, its not like super duper tiring bcz i still get like ~6-6:30 hrs of sleep (sometimes 7) but i still feel kinda tired bcz waking up early. My brain is just wired to wake up at this hour.

How can i make it so that i wake up at around 6:30 or 7?
