Sims bladder needs keeps going down too quickly

i originally downloaded all of sims 4 stuff from here and i just did the ultimate fix to update my game. Everything is running fine but my sims constantly have to pee. i lost count of how many times they've had bladder failure. i just thought my pregnant sim was just having going through the side effects but i noticed this was happening with my other sims too. Is this happening to other people? and If so how'd you fix it?
