Period on the 5th feb it lasted 3 days normal. the 25th i went toilet and had spotting, it got heavier and i'm still bleeding. what could it be?

Sometimes happens: 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. An ob-gyn doctor can check, if symptoms are worrisome or recurrent.
