Symptoms? Kinda TMI

MissK
I am on CD 19... I have had some slight cramps, diarreah, and have been feeling nauseous, not like actually throwing up but just a little nauseous... Is it too early to have symptoms? I realize its probably too early to test.. I don't know if I just "think" I am noticing symptoms because i want to?? Any advice or what do you think?
