I had my last period April 2012, In June found out that it was an utopic. Due to the size of the baby they had to remove my left fallopian tube. Following the surgery I received my first and only depo provera shot. It is now the end of February and I have not received my period, but for the last couple of weeks I have have pregnancy like symptoms. I went to the med center today and they have me a urine test it came back negative. Is it possible that I could still be pregnant? They refused to do a blood test on me.
