I have very sore, full breasts, skipped period, mood swings and cramping. i took 3 pregnancy tests and they all show a faint positive. am i pregnant?

Yes, congratulations: Pregnancy is the common cause of a missed period in women who have sex. One can confirm the pregnancy by repeating a home pregnancy next after another week. If still positive, schedule prenatal care visits with the doctor. If negative, but still having odd symptoms, contact the doctor to ask about the symptoms. Meanwhile, one should be on a prenatal vitamin.
