Am i going into early labor?

I have no idea if im going into labor or not... like the early signs of labor. I am 6 days over due, and i have been cramping real bad today. My stomach keeps on tightening and im getting shooting sharp like 4 second pains in my groin/inner thigh area and down my leg. Everytime my stomach gets hard i will get a dull painful pain in my lower back and my low abdomen will start cramping up, i am passing a tiny bit of gas and the feeling is making me feel like i have to pee all the time, so ill go and theres like barely any pee. Can someone help me out and tell me if this is labor? im freaking out ): i was 2 cm dilated yesterday and had a bloody show this morning
