My wife is having Spoting after  a week of normal Monthly cycle for two days. Seecond day it was just spots on her clothers. Just wanted to know if this is normal. She is also under the treatment of lung tuberclosis for 4months now. Also she isgaining a lot of weight after the treatment started. Before the diagnosis she also had mild Increased TSH level. Please advise if this needs a treatment. And what kind of test she can take for proper diagnosis.
