Am I pregnant?

I just got married in August and started my BC two weeks before I was married. I was skipping the placebo week so I haven't had a period since August. I just stopped taking my BC on October 14th. Usually I would start my period 2 days later but I haven't and it's October 25th. I've also had tender breasts, light cramps, nausea, dizziness, headaches, and I get up in the middle of the night to go number 1 which I didn't do before a couple weeks ago. Could I be pregnant or did my birth control just mess me up?
