Leaking amniotic fluid?? 40 weeks

I’m 40 weeks Is this amniotic fluid I’ve changed my underwear before this and i also had this same fluid on it every time I wipe dry it comes back I’ve been losing my mucus plug since yestuday could it just be discharge from that ? I went to l&d today and they swabbed me to check and it came back negative but it wasn’t as constant of a leak as now
