Carelessness: If you don't mind the chance of pregnancy this may be alright - a way to have a surprise. But, if you do mind, this is not good. Talk with your doctor about alternative birth control for forgetful or careless women. There are a wide variety to choose from and each has pros and cons. One may make it easier for you to be responsible about your lifestyle. Best!
