need advice

🙄😒

i’ve already talked to my doctor about getting my tubes tied, but i am not sure how this works. my oldest is 6, and i’m due for another baby next month. i don’t remember if they put you on birth control right after birth or you have to wait the 6 weeks then BC? all they said was i couldn’t get my tubes tied until my 6 week checkup, which is fine. do i need to be on BC before that or does it not matter? i also don’t know where to put this, so i apologize in advance.
