I am urinating more than usual

I usually could hold it for about 4+ hours but now ive been having the need to go within an hour to two hours. I accidentally peed on my bed woke up feeling i was peeing and ran the the bathroom. I dont have any pain down there and i will be going to the doctors for this just wanted to know if anyone has any opinions. I did have a light period that lasted 3-4 days. Which was 2 weeks ago and now this just started a week ago. I am obese but never had problems urinating before. What do you think?
