For some reason my body is telling me I need to pee when I have no pee left inside me if that makes sense, this only happened twice last night and tonight and it has only happened at night before bed, for example I just peed before getting into bed, but as I got in bed I felt the urge to pee again so I went back to the toilet and only a few drops came out, when I stood up I felt like I needed to pee again so I sat back down and this time nothing came out because there must be no pee left so why am I still feeling the urge to pee it’s so bizarre, I’m laying in bed now and still have the slight urge to pee? I’m 29 weeks pregnant
