Need advice... Pregnant?

Heather
I'm on day 35 of my cycle and still no period obviously 
I was nine days late last month and started on September 3rd but I moved from Ohio to California in August so I thought it was because of stress due to the move that I was late then 
Now I am even more late this month 
I did have sex without birth control and used the pull out method on my fertile days this month 
I took a test this morning and it was negative!!
Any advice ladies 
The test went from two lines to one line when I took it 
In a matter of seconds so I don't know if that means anything or if that's normal
