Frequent urination, extreme fatigue, sore nipples, acne, & hurts to press on tummy (uterus/ above pelvic bone). Could I be pregnant?

Yes. the answer to this question if you are sexually active and you have a uterus and ovaries is yes its possible. You can even get urine pregnancy tests at the dollar store, so check one when you get the time. If not ready to have a baby, probably time to see your GYN or family doc about getting on birth control and use a condom until then.
