Pregnancy ?'s: Menstrual cycles frequently vary in length for several reasons. A home pregnancy test may not be accurate on the first day of a "missed period". If your period does not occur in the next week, obtain a serum HCG test, to be certain about pregnancy. Ask your gyn physician about low dose oral BCP's, for more security about pregnancy options.
