A poop question?
There are a number of things that this could be. Start by looking at what you have been eating the last month. There might be something there that is loosening your bowels. Also look at what and how much you are drinking. Then also look at how much time you are spending in the heat. It can sometimes affect your gut.
If after looking at these things, you are still worried, call your clinic and talk to a nurse.
