On depo-provera shot for 8 months.feeling nauseous week before shot is due. been feeling nauseous for a week whenever i'm not eating. neg p test. preg?

No: If the nausea were from pregnancy, your test would be positive. The nausea must be from something else.

Very unlikely: If you are getting your shots on time pregnancy is very unlikely. There are a lot of other things that can cause nausea including stress and viruses but it would be unusual for Depo provera (medroxyprogesterone) to just start doing this after 8 months or for you to be pregnant.
