Was nervous for no reason(safe sex/ had a period), took a pregnancy test and it came out negative.. why am i still worried?

Still worried?: Learning why you were nervous at first -- and are still worried after your negative pregnancy test -- requires a 2-way conversation that isn't happening in this brief space. Discussing your worries with your own physician will be much more helpful to you because s/he can listen and ask pertinent questions, & then supply useful info. Perhaps you're worried about your partner or relationship?

Agree with Dr. P: If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine.
