If you ate a lot and all the exceed food and the rubbish will become crap if and only if your poo is the normal one. But if all your crap was in water form, it maybe you ate something that is no good for your body and your poo become the water form, so as three to five times in a day. Therefore, you just keep an eye on your poo whether it is the normal one for two to three days. If you also found some problems in your tummy, please go to see the doctor in advance.
