My hubby and I have been TTC about a month now and I'm 4DPO and AF is in 10 days, I have been having really unusual symptoms the past couple days. I have been getting hungry more often and today I had sudden chills followed by diarrhea out of no where and just a couple minutes later I feel hungry again. :-/ I know it could just be a touch of the flu, could it also be an early pregnancy sign?
