Light pink blood/dull red after sex

I know it's normal to sometimes have blood after sex (3rd kid,37w2d) but this is the first time my entire pregnancy I've seen blood. I guess this is more of a rant lol, I am so hoping I don't go into labor tonight or this weekend. 1) it's christmas, 2) I don't want to have him at 37 weeks & 3 my scheduled csection is NEXT Saturday, so if he comes before we have noone to watch our girls.. oh & im in S korea šŸ˜­šŸ˜­šŸ˜­ he's moving around though, but I swear I keep having light contractions. Sitting on my butt ans drinking water isn't really doing anything. It feels like hes digging away at my cervix occasionally( hes head down already). Stay in baby !šŸ˜„šŸ˜Ø
