What Does It Mean By PCR Of Menstural Blood For TB Has Come Out Positive?

Hi,I am 42 years of age. My height is 167 cms and weight is 65 kgs. I was diagnosed and treated for TB 8 years ago. Have been married for last 2 years and am not able to conceive despite best possible treatment. My tubes are fine and all my other reports are also normal. I already had a laprohystro examination and all is fine. I have just found that my PCR of menstural blood for TB has come out positive. What does this means and how long will the treatment continue. When will I be able to conceive? Please tell me.
