Labor?

Sarah
I have been having slight sharp pains when walking by my vagina n butt. Like a sharp cramp, then nothing for awhile. I have had a right tummy all day, vagina is literally sore to touch, (wiping I can feels it's slightly swollen). And my back is achy, and nipples are super sensitive and aching also!  Has any of these been a sign of labor for you! Help!!!
