I'm going crazy!! I keep noticing the smallest things and thinking it could be early preg symptoms

I've had a minor headache all day (not enough to take tylenol or anything). I'm hoping to see some implantation bleeding only I realize that not everyone gets that...unless most women do? I expect af around wednesday or thursday but kinda hoping it never shows!! I'm also unusually emotionall today...not extremely but little things are making me a little teary eyed.
What "symptoms" are you feeling while you wait like me???
