I bled a week early. my breasts are sore & i've noticed way more bumps around my nipples. neg hpt day of expected period. could i still be pregnant?

Maybe. Maybe not.: One can re-test in a week. An early menstrual period may be caused by changes in hormone levels, which can be due to anxiety, stress, overworking, intense exercise, fatigue, or excessive weight gain/loss. If pregnancy happens, a bit of spotting sometimes occurs 9-14 days after conception and may seem to a woman that she's starting an early period. If symptoms continue she can see an ob-gyn doctor.
