Pregnancy: If you are sexually active and not using birth control you may be pregnant . Do a home pregnancy test.

Late for cycle ?yes: yes, do a HPT if you are nauseated and any other pregnancy symptoms, even if u bleed irregularly. u never know... especially if u are not on any protection.. btw, maybe u should be on something, if you don't really plan on a baby now..
