Hey thanks for your faith in the health care magic.i have gone through your question and understood your problem.
Yes, it is sometimes possible to have tuberculosis, and yet test negative on the conventional laboratory test.
Evidence of tubercles directly seen on DL and
hysteroscopy is the best proof of
genital tuberculosis.
SHe is right to recommend anti tubercular treatment for you, based on the directly visible evidence.
It is definitely possible to conceive a baby while on
AKT.
Just wait for the initial two months of AKT 4 to get over.
Then you can start trying for
pregnancy.
If the tubes are open, there should be no hitch there.
There is no complication to the baby while you are on AKT 3.
Hope I have answered your query. If you like my answers and wish me to answer in future, bring it to my attention
