I have been to the DR's today as I have had lower left abdominal pain, that shoots down my leg. My period is 3 days late and the doctor examined me and did a urine test for pregnancy (negative). He siad there's nothing wrong with me and its probably menstrual cramps. I have never had menstraul cramps before, Im still worried. I have been trying for baby, had miscarraige in sept. He said that would not cause this pain... should I stop stressing?
