Could it just be normal early cramping?

It often is — mild, central cramping in early pregnancy is common. The features that change the picture are severity, one-sidedness, shoulder-tip pain, and feeling faint. With those, get assessed rather than reasoning it out.

I have no pain, just spotting. Do I need the ER?

Not necessarily the ER, but do call your provider today — spotting alone warrants assessment, and part of what that assessment does is rule this out before it becomes urgent.

Did anything I did cause this?

No. It's about where the embryo implanted, which is not something behavior controls. Prior tubal damage or infection raises risk, but plenty of ectopics happen with no risk factors at all.

Ectopic pregnancy: the one that can't wait

This is the shortest page here on purpose, because if it applies to you the only useful thing it can do is get you moving.

Go now if

You have a positive pregnancy test, or think you could be pregnant, plus any of: severe abdominal pain, pain clearly on one side, pain at the tip of your shoulder, dizziness, fainting or feeling like you might, or heavy bleeding. Go to an emergency department. Do not drive yourself if you feel faint.

Shoulder-tip pain is the one people don't recognize. Blood in the abdomen irritates the nerve that also serves the shoulder, so pain shows up somewhere apparently unrelated. With a positive test, it is treated as internal bleeding until proven otherwise.

What it is

A fertilised egg has implanted somewhere other than the lining of the uterus — most often in a fallopian tube, which cannot stretch to accommodate a growing pregnancy. There is no version of this where the pregnancy continues safely, and no intervention that relocates it. That is a genuinely hard sentence to read, and softening it would only cost time.

Early on it can look ordinary: a positive test, maybe some spotting, maybe mild cramping. That is precisely why bleeding or unusual pain in early pregnancy gets reported rather than watched.

How it's treated

Caught early, often with medication (methotrexate) that stops the pregnancy developing, avoiding surgery entirely. Later, or if a tube has ruptured, surgery — sometimes removing the tube. Diagnosis usually involves hCG blood tests, often repeated, plus an ultrasound; a pregnancy that can't be seen in the uterus when hCG says it should be visible is the classic picture.

Afterwards

Most people who have had an ectopic pregnancy go on to have a healthy pregnancy later, including many who have lost a tube. You will usually be advised to tell your provider early in any future pregnancy so an early scan can confirm the location — which is a reasonable precaution, not a prediction.

This is also a real loss, and it is common to have it treated purely as a medical emergency by everyone around you. Both things are true at once.
