how long has this been going on? sometimes, we women experience hormonal changes which reflects in our periods. Even stresses affects our periods. If you are worried about being pregnant..to ease your fears..do a pregnancy test. Otherwise..please consult the doctor.

my dear TS..suicide is not an answer to any problem.

It may just be hormonal change or due to stress as you are in college. I suggest, you go see a doctor and check. If you want to do any initial check, just buy a pregnancy test to ease your main fear.

Next time...just take safety precaution so that it doesn't put you into this situation again.
