First signs of an ectopic pregnancy may include:
- Vaginal bleeding, which may be light.
- Abdominal (belly) pain or pelvic pain, usually 6 to 8 weeks after a missed period.
As an ectopic pregnancy progresses, though, other symptoms may develop, including:
- Belly pain or pelvic pain that may get worse with movement or straining. It may occur sharply on one side at first and then spread throughout the pelvic region.
- Heavy or severe vaginal bleeding.
- Pain with intercourse or during a pelvic exam.
- Dizziness, lightheadedness, or fainting (syncope) caused by internal bleeding.
- Signs of shock.
- Shoulder pain caused by bleeding into the abdomen under the diaphragm. The bleeding irritates the diaphragm and is experienced as shoulder pain.
