curious

So my last period was oct 11 I haven't had one since an I've token tests an some have faint lines an some don't have anything.
I know I prob should just go the doc but I'm to nervous.
But lately I haven't felt good an been moody an just blah .
I've got th signs I could be pregnant 
Well just recently for past 3 days I have had a horrible ear ache could it be a sign of pregnancy also? 
Just curious
