Low white blood cell count

Has anyone been pregnant and have had low white blood cell count. I am 8w3d. Mine came out very low according to the Dr. He said with the cells being so low he would expect to see a very sickly person. I feel perfectly fine with normal pregnancy symptoms (nausea, fatigue, and hunger). He had me redo my blood tests and I get the results on Monday but I'm freaking out a little. This didnt happen with baby#1.
