Infertility. Uterine cavity and tube?

I have miscarriage in july 15. I tried to conceive from last two year. I was suffering from genital tb the treatment start from sep 15 & completed 9 month tb treatment in may 16 . I had hsg test in july 16. In report uterus have no abnormality but my left tube is blocked. I saw in a x-ray my uterus is tilted to the left. My dr suggest me two month follicular monitoring and after that diagnostic lab+hystroscopy. I had 4 time follicular monitoring, all are ovulating cycle. 3 time my right overy ovulate and one time left. now my question are: (1) Is tilted uterus cause of infertility? (2) Is two months try sufficient to conceive? or i should try for more cycle? (3) why hysteroscopy necessary for me? (4) is hsg doesn't give information about uterine cavity and tube? (5) What are my chances to become pregnant.
