Good news first — on Thyronorm, a slightly elevated Total T4 with a normal
TSH (yours is 3.146, well within range) is actually expected and not a sign of overdose. TSH is the reliable marker when you’re on
thyroid replacement, and yours is controlled. So your dose looks appropriate, no need to panic about the T4 number.
For the missed period with a negative
beta hCG — at 41, the most common reasons are perimenopausal hormonal changes, stress, or sometimes thyroid-related cycle shifts. Pregnancy is reliably ruled out if the test was done after the due date passed. Nothing alarming in what you’ve shared, but the menstrual change deserves proper evaluation rather than guesswork.
Next Steps
• Continue Thyronorm 75 mcg as is — don’t stop or self-adjust
• Next time, get Free T4 (FT4) along with TSH — it’s more accurate than Total T4 when you’re on levothyroxine
• If period still hasn’t come in another 7-10 days, repeat the beta hCG once more just to be doubly sure
• For the missed period: an
FSH,
LH,
prolactin, and a pelvic ultrasound would give clarity — these together tell us whether it’s perimenopause starting, a hormonal imbalance, or something else
• These results are best reviewed together in a consultation so the thyroid and menstrual picture can be connected rather than looked at separately
Helpful Tips / Word of Caution
• Take Thyronorm on an empty stomach, 30-45 minutes before food, tea, or coffee — only with plain water
• Keep a 4-hour gap from
calcium or iron supplements
• Don’t stop the medication even if you feel completely fine — hypothyroidism management is long-term
• A short consultation would help me look at the full report (the 7-page
health checkup) and tie it together with your symptoms — happy to guide you through it whenever you’re ready
