Bloody cervical mucous and cramps 2-3 days before period is due. is this normal?

It may just be an: earlier period. Irregular periods and spotting could mean you may have some hormonal imbalance that could be affected by many different factors, including age (if approaching menopause?), nutrition, illness, exercise (or lack of it), body girth, psychological well-being, stress, season, or simple fluctuations of other related hormones (thyroid for example). U should check a preg test 2.
