Is this my fluid or urine leaking?

So I went pee then I was walking around and sat on the floor to fold laundry and I felt a little bit of fluid come out. Went to the bathroom and the top of my panty liner was abit wet and maybe a nickle size spot on my underwear was wet. I changed the panty liner and have been walking around and even squatted and coughed and nothing else came out.
