Hi,
At age 41, irregular periods, spotting or lighter bleeding are quite common because this age falls in the perimenopause phase (time before menopause). Hormonal fluctuations are the most frequent reason, but
thyroid issues, stress, weight changes, or uterine problems (like fibroid, polyp, endometrial thickening) can also cause it.
Medicines usually given are hormonal tablets (progesterone or combined pills), sometimes iron if anemia develops. But exact medicine depends on ultrasound and blood test results, so self-start is not advised.
Next steps:
Get hemoglobin, thyroid profile, pelvic ultrasound.
Track your bleeding pattern (dates, flow).
Consult a gynecologist for proper prescription.
Most of the time it’s not serious at this age, but regular check-up is important to rule out other causes.
I hope it help you
