So I had some really bad pains in my left side a week ago. I've still been getting them on and off. I went to the doctor the day I had the bad pains but I was there for another reason so she completely ignored the fact that I was in horrible pain. She told me it could be ectopic pregnancy but said I'd have to go to the ER if I wanted any help for it.

I'm wondering if any one knows how early you can start getting symptoms from this? I feel that the odds of me being pregnant is very low but I'm worried at the same time.
