A combination of the stress and travelling can definitely throw your cycle off course. In order to get to school, did you travel by plane? If so, this could have a huge impact on your cycle, on top of being worried about school, financial problems and of course, whether or not you're pregnant.

What you mentioned does have some similarities to pregnancy, but they also could be from tons of other things, including this cold that you've had for the past week. You haven't experienced any other symptoms.

In any case, you need to get hold of a pregnancy test. If you're on campus, you could always visit the nurses office, or the hospital on campus to get a pregnancy test done there instead of trying to purchase one at the store. But, one should be taken sooner rather than later.
