Hi, I am 27 years old and trying to get pregnant. I had an missed abortion of 3 months about 8 months back and a month back I have been disgnosed with TB in uterus. Have been prescribed SKT-4 along with aciloc, panpol. Started the treatment on 10th Nov'11. My LMP was on 1st Nov'11. Usually my cycle length is 29/30 days but till now i have'nt got my period..(today is 2nd December). Can TB medication cause this delay?
