Bloody show??

I’m almost 37 weeks... baby is measuring two weeks ahead though, and I just wiped and had this. Is it my bloody show? There was a little more too later after the pic... I’ve had an increased amount of mucus the last couple of days and now spotting. Called the nurses hotline and they said it sounds like I’m losing my mucus plug and that it is the bloody show. If it is, how far away could labor be? I’ve been cramping all day but nothing super painful, lightening crotch from hell, and I have bad low back pain that radiates about every 20 mins. Help :(
