Rubella IgG , CMV IgG & Toxo IgG affect pregnancy

Hello,

I plan to have a baby in this Jan 2011, and I went to have my blood tested to make sure that I can have a safe and successful pregnancy. The result showed that CMV IgG: 2.10 (Normal:<1 index), Toxo IgG: 85.12 (Normal:<30 UI/ml) and Rubella IgG: 444.4 (Normal: <10 UI/ml), and because of these three virus, the doctor advised me not to have baby yet. He also give me treatment via taking medicine for one month and then 6 months later,I must have my blood tested again, and if the figures is decreased to normal level, then I can have a baby. Actually, I used to be pregnant, but just after one week I relized it miscarriage (around two years). My question is that does my blood test result is caused by my past miscarriage? if not why? Is it dangerous I have baby at this time?

I really appreciate for your response.

Thanks
