Bloody show without mucus?

I am 38+5 today. Woke up and had a bloody spot on my pyjamas - more than spotting, like a lighter period. Now it is just bits of brown blood coming out. I am not sure if this is my bloody show if it’s just blood without any mucus plug? Has anyone experienced this and how long was it until labor? (I did call my hospital and the doc on call was super calm like “yeah normal” but didn’t tell me what I should think of it. I go in tomorrow)
