am 11DPO. I took a clear blue pregnancy test this morning and it came back "not pregnant" My period is due Thursday and today is Monday, do any of you think I could still be pregnant? Only symptoms I have are slightly sore nipples when touched. A little bit of nausea, but can still eat. Some diarrhea earlier today. This is my second month trying so dont want to give up hope. Just want to see what you ladies have to say.
