I got on my last period on December 24, 2011. I have a 32 day cycle. I was supposed to get on by January 25th. I did have unprotected sex around my ovulation, and I have took a pregnancy test and it came out negative. Could I be pregnant?

Give it a bit more time as your cycle may just be off a bit. If still no period after another week, try another test. If negative, see what happens when you would expect a period for February. While not the norm for most women, it can happen that a month gets skipped now and then.

Yes, give it another week or two, and if no period, do another test. Sometimes it does not work on a exact schedule.
