Hey...have you recently had a heavy period, as your doctor should have explained more clearly you could have miscarried and there are still HCG levels in your body. This would cause the pregnancy test to show neither a positive or negative result. I have had this happen to me in the past and as i suffer from bad cramps on my period and heavy bleeding it was easy for me conguse the two.
Hi. I have never had this happen to me but it seems like he was saying that you may have had a chemical pregnancy. Hopefully someone else will respond with more information.
