Can i be leaking amniotic fluid?

I'll be 38 weeks tomorrow and early i had a panty liner on. When i stood up, i felt a little gush. Then i went to the bathroom to check the liner and there was fluid on there, it looked like there was a tint of yellow. There was no smell to it. So then i changed into another panty liner. 30 mins later i checked and it was also wet. Now, i have no panty liner on, i would find wet spots on my panties. Of course the whole underwear isnt wet, but its just a wet spot. I swear to god its not pee, because if it was i would know. Do you think this could be amniotic fluid?its been every 30 min that i find a spot on my undies.
