High White Blood Cell Count in Semen - Enterococcus Faecalis

I recently got my results for a semen analysis back and I found out that I had a high white blood cell count.  They cultured it and found that Enterococcus Faecalis was the culprit.  My only symptom is a very slight burning after I ejaculate sometimes, and that only happens about once or twice a month (I have intercouse about 3-4 times a week).  Also, when they did the semen analysis, they found the sperm to be healthy.  Motility, volume, and morphology were all normal.  It has been about 4-5 months since the test and we are still not pregnant.  I was also put on ampicillin 4x a day for 10 days.  I did not get rechecked because of the good sperm results.  I'm wondering if I should get retested.  Has anyone been in this situation, where there are high white blood cell counts in semen and were still able to get pregnant??  Thanks.
