Leaking amniotic fluid or pee?

While at work I wen to use the restroom and peed after I whipped myself and pulled my pants back up, washed my hands and walked out I felt like something leaked out I didn't think much of it but it was enough to soak through my panties and into my scrub pants! I'm only 19 weeks and 2 days I'm worried as to if its amniotic fluid or pee!!! 😔😔
