EARLY SIGNS??

**TMI** I am not due for AF until the 12/27, the last week I've had green diarrhea (never had before), headaches at night (not usual) no appetite, lost 5 pounds (I assume from the diarrhea), last night and today lower noticeable back aches, and all week on and off left ovary pinching. I'm not sick, no fever, didn't eat anything wild. Anyone else have diarrhea as a early pregnancy symptom??
