Abnormal Cramps
Worsening and unbearable cramps, if accompanied with pelvic pain, fever, headache, dizziness, fatigue and presence of blood clots in urine could be an early ectopic pregnancy symptom. It happens when the egg implants itself in the Fallopian tube, cervix, or abdomen instead of the uterus. In this case, consult a doctor at once as it's a serious complication.
