Since your TSH is still elevated at 7.98, it indicates your body needs a slightly higher dose than your current 25 mcg of Thyronorm (levothyroxine). While increasing to 50 mcg is a logical next step, please consult your prescribing doctor before making this change. They will confirm the correct dose for your body and schedule a follow-up blood test in 6 to 8 weeks to ensure your levels safely normalize.

During early pregnancy, your body naturally needs more thyroid hormone, which is why your doctor increased your Thyronorm (levothyroxine) dose from 50 to 100 micrograms. A TSH of 6.19 is only mildly elevated, and because your other thyroid levels are normal, your baby is well-protected. Increasing your dose now ensures your baby has all the support they need for healthy brain and body development. You caught this early, and this proactive adjustment is highly effective.

You've started Thyronorm (levothyroxine) at a gentle 12.5 mcg dose for your mildly elevated TSH. It takes time for this hormone to build up in your body. Most people begin to feel a lift in their energy and muscle strength within 2 to 4 weeks, with full benefits usually felt around 6 to 8 weeks. Your doctor will likely recheck your blood levels then to see if any adjustment is needed.

While taking Thyronorm 75 (levothyroxine) to balance your thyroid levels, safe weight gain is best achieved through a nutrient-dense diet rich in healthy fats, proteins, and complex carbohydrates, alongside gentle strength training. As long as your thyroid hormone levels are kept in the optimal target range with your medication, your ability to conceive and have a healthy pregnancy should not be negatively impacted. When planning a pregnancy, just share this with your doctor, as medication dose adjustments are very common and perfectly safe.

Your light, one-day period is most likely due to skipping your usual progesterone pills, like Regesterone (norethisterone). Progesterone helps build the uterine lining, so missing it can lead to a much lighter bleed. Additionally, starting your new thyroid medication, Thyronorm (levothyroxine), helps regulate your hormones, which can also naturally alter your menstrual flow as your body adjusts. Both factors are very common reasons for this change and nothing to worry about. Please discuss this with your doctor to coordinate your treatments safely.

Take your Thyronorm (levothyroxine) on an empty stomach with water, 30 to 60 minutes before breakfast. Please avoid soy, high-fiber foods, calcium, and iron supplements close to your dose, as they can block its absorption. As your thyroid levels stabilize with this daily medication, your metabolism will improve, which gently helps with weight management, eases fatigue, and reduces anxiety. Be patient with yourself, as it takes a few weeks to feel the full benefits.
