i can’t go to bed until i do certain things can anyone help?

I’ve noticed this new obsession with having to pee right before bed, like even if I have to pee a little I can’t fall asleep until my bladder is completely empty. Anyone else have a problem like this or knows how to cope?

18+ pls!!! pls reply if u can (superrrrr tmi, pls don’t read if it’ll make you uncomfortable) since struggling with ocd, i have rules around the likes of m^sturbation and sexual stuff because i think too much into it now. one of the rules is that exact day i cant have seen or been around children because otherwise ill get intrusive thoughts that ive done it because of that (it isnt and never has been, before all of this i was able to engage in this stuff without any worry because it never crossed my mind). i cant have seen one the day before either or the day after actually engaging in that stuff because otherwise my mind plays tricks on me. i wanted to yk today because it makes me tired and most of the time helps me sleep but im worried i cant now because my mum and i watched a show and there was a quick clip of a child in it and my for you page on tiktok is things related to the genocide in gaza which obviously on some posts has pictures too that i’ve seen while interacting with the posts (like, commenting and reposting. thought i should state this bc i dont want it to sound like i meant anything else) so because now ive seen them i feel incredibly guilty and that if i am to yk, they’ll somehow link and be proof im this bad person. (Also should state i mean m^sturbate to ADULT content, when i’ve seen these posts i haven’t got aroused or anything. i’m just worried that bc ive seen stuff related to children today it’ll be bad of me to engage in that sort of thing to help me sleep)

English is my second language,so please bear with me if there are any shortcomings. My OCD is manifested in the need to go to the bathroom before going to bed every time, but after each urination, I worry that I will have to go to the bathroom again because I feel that I seem haven't finished. This will affect my sleep by repeatedly entering and exiting the bathroom. It takes me more than half an hour to go to the bathroom before going to bed every time, and I have to fight with myself to tell myself that I have finished and don't have any more urine, so I can sleep peacefully. However, it takes countless times to comfort myself.I tried to quickly finish urinating and then immediately step out of the bathroom, but every time I had the thought of "I still feel like I have a little more urine, should I squat again?" I felt like I was nailed to the toilet and couldn't get out. (Our toilets here are squat toilets), which greatly shortened my daily sleep time. Moreover, after using the toilet, I would continue to use my phone to relieve anxiety and develop a habit of staying up late, which undoubtedly exacerbated my symptoms.It's like a process of constantly pursuing certainty, making sure that I have completely emptied my bladder, but this pursuit is morbid, and I can't accept its uncertainty.I don't know what to do. Do you have any solutions?
