Could I be pregnant?

[nicole_L183]

I had sex for the first time two weeks ago and again last week. Condoms and the withdrawal method were used both times. After each time, we filled the condom with water to make sure that there weren't any leaks. I am not on any other birth control. I have been having some brown spotting for the past week but no cramps or normal period symptoms. I've been under a lot more stress during the past few weeks, but my stress has never caused abnormal spotting. My period is due next week. Should I be worried about the spotting? Is there any way I could be pregnant?
