Symptoms?

I was due on yesterday but nothing yet. I dont know if its wishful thinking or if i have early symptoms, i feel wierd, i cant really describe it, ive been ridiculously moody, headaches, slight nausea, and the strangest feeling around my belly button. We've been trying for 2 years, hospital has offered to go for IVF but i dont want to go down that route yet. Anyone feel "wierd"?
