Normally it takes 9 months with 3 months plus and minus with just medication.
It depends if it is infectious or non infectious in your case, about which Doctor can inform you after seeing your x-ray report.
But nothing to worry about, just remember one thing, take proper and regular does of medication as prescribed.
