36 weeks pregnant....please any help is appreciated! 10 pts!!!!?

Not sure if its because labor is close, or if its just from being in late pregnancy, but my BH are getting SO much stronger, they take my breath away, and changing positions doesnt help, also im having a lot of soft stool BMs sorry tmi. I'm having a lot more discharge and have to wear a panty liner all the time, my back is KILLING me, and it hasn't at all this pregnancy up until now, and I get random Sharp pains and pressure in my crotch, sometimes it actually feels like her head is trying to push through my cervix, and I'm getting sharp pains in my inner thighs. I had tons of energy, but now I'm completely exhausted....am I close to labor, or is this normal for 36 weeks? And do you know any natural ways to help speed up labor? My Dr said the baby is perfect right now, but didnt tell me if I was dilated or effaced, this is my 2nd child and i dont remember any of this with him......help plz?!
