Hi! I'm not sure why you wouldn't be having a period. I know that they say that for some women the Depo shot really messes with them but I'd think 6 months after the shot things would start becoming more normal. Did you have bad cramps before having the essure procedure? Did you have the follow up test? My best advice is that you know your body. You know how you feel. No one else feels what you feel. If you don't feel that something is right and your doctor is not helping you then you might want to consider finding someone who will help you get some answers. Trust yourself.
