I haven’t run into the issue of peeing more than normal when I have PMS. Unfortunately, I have experienced the symptoms of a bladder infection. I’m not sure whether or not your peeing a lot is related to possibly having a bladder infection, but I wanted to throw it out there so that you’re aware and can maybe look out for the symptoms, which include the constant feeling like you’ll pee your pants, a slight burning each time you pee, and the frustrating reality that after stampeding to the bathroom, there’s only a drop of pee that needed to come out. If that doesn’t sound like what you’re experiencing, it may be that having to pee more than usual is actually related to your period. Dr. Molly can provide more insight.
