Iv had my periods for 2 weeks and 3 days and i have cramps of period pains still should i worry about this ?

Not normal period..: Your period should not last more that 7 days reason why I think you should get checked in order to find out why were you bleeding for so long. Things to consider: pregnancy, infection, hormonal abnormalities. Try to see a GYN provider for this.

Prolonged period: If your period has lasted more than 2 weeks with painful cramps and this is unusual for you, you should consult your gynecologist.
