how long until t levels are baseline?

when i went away to college i started taking t, but stopped about 3 weeks before my flight back home in the hopes it would level out so i could be prepared if my parents wanted my hormones tested. i knew i made a mistake in giving myself such little time but it was already done. by the time my flight was approaching my mom asked if i wanted to get on birth control to help with my acne, and i agreed, because i was also pretty active and it wouldve benefitted me. i was unaware all of the lab work would go to her, including hormone levels (going in i didnt even know they were going to do bloodwork, it was a pretty misinformed decision on my end) and now im freaking out. the day i was tested was about 4 weeks after stopping t i believe, and i had my first normal period the night of, i just want to know based on others' experiences what their hormone levels looked like a few weeks off t to gauge how fucked i am. the results are still pending.

i've been doing it via weekly injection at standard dose (50 mg/week)

and sorry if this is a bit illegible im just in a panicked state
