Eptopic pregnancy or just paranoid, how to know?

How far along?: Here's a link: http://www.webmd.com/baby/tc/ectopic-pregnancy-symptoms Early along there will be vaginal bleeding and abdominal pain - both get worse over weeks. Then, dizziness, pain during sex or exam, 'shock' symptoms, even shoulder pain. Your doctor can diagnose this and should see you if you are concerned. It can be dangerous if not treated. Best wishes.
