Certain I just had bloody show. What do I do now?!

I'm currently 38+6 and certain that I just had bloody show. I was on the toilet and on my tissue paper were streaks of discharge or my plug, mixed with red blood. No clots or anything just blood. I'm not having any contractions. I'm home alone and my SO won't be home from work until 11 pm. I looked up what to do after bloody show is present and it says labor can start within a few hours or days after. Should I just wait it out or call my SO home?
