Missed periods after starting treatment for genital tuberculosis can happen for several reasons, and it does not always mean pregnancy, especially if your pregnancy test is negative. Genital tuberculosis itself can affect the reproductive organs and may disturb the normal menstrual cycle. In some women, the infection can affect the lining of the uterus, ovaries, or hormonal balance, which may lead to irregular periods, lighter periods, or even temporary absence of menstruation. In addition, physical stress, weight loss, poor nutrition, emotional stress, and the body's response to a long-term illness can also contribute to missed periods during treatment. Anti-tubercular treatment (ATT) medicines are generally important and should not be stopped without medical advice. Although these medicines are not the most common direct cause of missed periods, the illness and overall stress on the body during treatment can affect the cycle. It is important to continue your medicines regularly as prescribed because incomplete treatment may worsen the infection or delay recovery. You should follow up with your gynaecologist or treating doctor for further evaluation. They may advise a repeat pregnancy test after some time, pelvic ultrasound, hormonal tests, or other investigations if the periods do not return. Maintaining a healthy diet, proper rest, hydration, and managing stress may also help support recovery and hormonal balance. Seek medical attention sooner if you develop severe abdominal pain, fever, abnormal vaginal discharge, heavy bleeding, or significant weight loss. With proper treatment and follow-up, menstrual cycles often improve over time, although recovery may vary depending on the extent of the infection.
