What might the very beginning symptoms of an ectopic pregnancy feel like?

Pain and bleeding: An ectopic pregnancy may start out feeling just like a normal pregnancy. However, once the embryo grows large enough to put pressure on the fallopian tube, you may start to have crampy abdominal or pelvic pain and vaginal bleeding (often after having missed a period). If this is you then you need to get to the er right away as this can become very serious very quickly if not treated properly.
