My last period started on sep 11and didnt come back till now. took a home preg test yestrdy it was negative is there anything wrong ?

Don't know how: long your menstrual cycle normally is? If you feel healthy & are experiencing a normal period (for you) - it doesn't necessarily mean anything is wrong. Reasons for missed/late periods: low body weight, obesity, marked weight ^ or v, over-exercise, endurance athletics, breast-feeding, ^ stress, illness, eating disorders (bulimia or anorexia), anovulatory cycle (no egg released), travel, hormone
