I been having really bad stomach pains, milk coming out of my nipples, diahrea. So I went to the doctors and they told me my iud is to low but nothing serious . To me that is serious . Could that cause problems ? What are the chances of me being pregnant with the iud being so low ?

That's not very good. You need to go and see a Specialist! Something went wrong with a friend of mine who had the same problem like you. Sue the doctor while you're at it for Poor Misguiding.

Have you tried a pregnancy test? If not, you could do so and see what results you get. Did they do an ultrasound, pelvic exam, or urine test at the doctor's office? If so, a pregnancy would most likely have been noted. Have you had any children before? There can be other reasons for your discomforts other than pregnancy.
