Bloody show/mucus plug or irritation from sex?

My husband and I had sex at around 7pm, then around 11pm I got up and had a small gush of liquid come out with a tinge of blood and called l&d who said it’s nothing to worry about because I did not continue to leak. It’s now 4am and when I wipe there’s a ton of thick mucus tinged with very light blood. He did not cum in me so it’s definitely not semen. Is this my bloody show? How long before labor?
