Yes, your elevated TSH of 10.36 indicates your underactive thyroid is not yet fully controlled with your current 25 mcg dose of Thyronorm (levothyroxine). An underactive thyroid frequently disrupts menstrual cycles, leading to prolonged or frequent bleeding. It is very reassuring that your ultrasound and hemoglobin are normal, as this rules out structural issues. This suggests the hormonal imbalance is the primary cause. I highly recommend sharing these results with your doctor, as they will likely need to adjust your levothyroxine dose to help bring your TSH back to normal, which should help regulate your periods.

Yes, you can safely take dydrogesterone (Duphaston) alongside folic acid and levothyroxine (Thyronorm). There are no harmful interactions between them. Just remember to take your levothyroxine on an empty stomach in the morning for best absorption. While dydrogesterone is safe and often used to support pregnancy, using it to postpone your period while trying to conceive can disrupt your natural cycle and ovulation tracking. It is best to discuss this with your gynecologist first to ensure it aligns with your conception plans.

While it is common to see symptoms fluctuate as your body adjusts, please do not increase your dose of Thyronorm 50 (levothyroxine) on your own. Thyroid medication dosage must be precisely tailored based on blood tests, such as your TSH levels. Changing your dose without medical supervision can cause unwanted side effects. I highly recommend contacting your doctor to check your thyroid levels so they can safely adjust your prescription if needed. In the meantime, staying well-hydrated and increasing dietary fiber can help bring you some gentle relief.

Your thyroid test results are normal. This indicates that your current dose of Thyronorm 75 (levothyroxine) is working perfectly to keep your hormone levels balanced. Generally, when your lab results are in the normal range, it means your dosage is correct and does not need to be changed. However, please continue taking your medication as prescribed and consult your doctor to confirm before making any adjustments.

It is very common for thyroid levels to fluctuate postpartum. Since your TSH is elevated at 39 mIU/L, your body is asking for more thyroid hormone. Generally, restarting your previous dose of levothyroxine (Thyronorm) at 50 mcg daily is a safe and standard starting point. Since your free T4 is currently normal, restarting this dose will help gently bring your levels back into balance. We will want to recheck your blood levels in about 6 to 8 weeks to make sure it is the perfect fit. Please connect with your doctor to safely restart.

Since your thyroid levels are well-managed with levothyroxine (Thyronorm), that is wonderful news. After a miscarriage, your body's hormones can take several cycles to fully reset, which can temporarily delay your periods and ovulation, even if standard tests look normal. Give your body a little gentle time to heal. I highly recommend discussing a cycle-tracking plan with your doctor to help guide you on this journey.
