Possible to not have any symptoms ?

Af is due feb 6th but I feel nothing different. Except for today I have a pulsating headache everytime I stand up. But is it possible to not have any symptoms but still be pregnant? I know I can't take a test for a few days yet, but I'm reading about all these symptoms that everyone is having and I'm not getting any. I'm losing hope that this could be my month :(
