Anyone else have these symptoms?

I've had a backache and menstral like cramps for about a day now. Also have a lot of discharge to where it trickles when I stand up. Just got back from the doctor and the tests they ran show its cervical and vaginal discharge. She said there's a chance it's amniotic and if it is I'll more than likely just go into labor. Otherwise it's strictly cervical from dilation.
