Anyone else experience this & went into labor soon after?

This is my first pregnancy and I'm currently 38+6 today. However, for the past few days along with sharp pains and minor back pain it feels like I'm getting my period. 
What I mean by that is the dull feeling some girls might have when you're actually shedding blood and have a flow? 
It feels kind of hard to explain but im sure you get the picture lol
But has anyone else experienced this and went into labor pretty soon after?
Thanks ❤️
