my bladder is never empty

i swear i go to the restroom and sit there for soo long bc i know i have a lot more urine in my bladder and five minutes after getting up from the toilet, im gonna have to go again 🙃 and i literally do everything to try and completely empty my bladder but i can literally always feel that there is still pee that just doesnt wanna come out 😕 i'll literally push like im pooping just trying to get every last drop of pee lol.. and then ill switch positions a few times. the other day i actually had to pee soooo bad and when i got to the restroom, literally nothing came out and i was like hell nah, so i lifted my stomach up and tried again and was actually able to pee 😂😂😂 im ready for my son to be in my arms instead of pushing on my bladder so i can feel normal again
