41wks? Sex?

Crystal • 28, One 👼🏻 & One 🌈 Child & Baby on the way🤰🏻
Ok so I'm 41wks today. Havnt had any signs of labor happening. Had sex couple hours again was no bleeding and just woke up to having pains in lower abdomen and then pain in my lower back and when I go toilet and wipe there is blood? I guess I'm asking what happen to people that went into labor after sex if that what this is?
