Not feeling pregnant today... should I be worried??

The past few days I've noticed cramps & nausea, figured they were normal symptoms. Woke up this morning with the weird feeling that I may not be preggers... no symptoms, just feeling a little empty & extremely moody...

I have my very first appointment with my midwife in a few days, not expecting to have an ultrasound until further appointments...

Anyother ladies feeling the same, or went through the same??
