pregnant?

I went to the doctor and they drew blood but also made me urine in a cup. The doctor said the urine came back negative for pregnancy see but the blood test came back inconclusive. She said that my white blood count was really high and it only gets that high when pure pregnant but the lab said the pregnancy test was negative. She wants me to come back in next week to redo the blood because she said it's possible I am pregnant but to earlier to prove positive in test. Idk what do you think??
