Morning pill was taken it caused bleeding now the period is 2 weeks late. the pregnancy test was negative. could there be a pregnancy?

Possible pregnancy: It is possible that the morning after pill changed the menstrual cycle, causing early bleeding and a late menses. Pregnancy is still a possibility, so you should consider having another early morning pregnancy test done again in 1-2 weeks. If you do not want to become pregnant, use condoms and/or a vaginal spermicide, and consider a visit to a health provider for other birth control options.
