You may have noticed some irregularities in your period, either the timing or the flow. Often a pregnancy test will test negative because an ectopic releases less hcg (pregnancy hormone) into your system. You may have some stabbing pain coming from either side of your pelvic region, as well as some basic pregnancy symptoms. Or you might not have any symptoms until the pregnancy ruptures through the Fallopian tube, in which case it becomes an emergency because you start hemorrhaging internally. If you suspect you have an ectopic pregnancy, see a doctor immediately. They will most likely do a blood hcg test and an ultrasound. When caught early, there is a pill called misopristol that they will give you so your body sheds the pregnancy out without any surgery. For many women this is difficult because they compare it to abortion, however, there is too much risk to both mother and pregnancy's life for it to continue. No doctor will say it's safe or ok to keep, there is only one recorded case of both mother and baby surviving, and one case where the mother lived and the baby died because she was unable to deliver it. This is a tough situation, but it's best to see a doctor ASAP to avoid risk of hemorrhage and surgery. IF YOU ARE HAVING SEVERE PAIN OR SUDDEN HEAVY BLEEDING GO TO A HOSPITAL NOW. Risks of surgery involve losing a Fallopian tube, ovary, or uterus, as well as hemorrhaging and rarely but potentially death... And that would be from not getting care quickly enough after starting to bleed internally. It's a tough situation, if you do have an ectopic pregancy or any pregnancy be sure to talk to someone for support because you'll need them. Good luck!
