slightly tmi: leaking fluid?

Hailey
I am 40+2 and went to get up to use the bathroom and suddenly leaked through my shorts, resulting in these two spots. It doesn't smell like urine. It really doesn't smell like much of anything. I'm a FTM and not sure if it is amniotic fluid or just watery discharge. My SO doesn't get home from work for another 4 hours and I don't want to make him come home early if it's not an emergency. It's not accompanied by any contractions, just mild cramps throughout the day.
