What could be causing my period to be five days late with symptoms like mild cramps, mood swings, nausea, anxiety, and feeling hot, even though my pregnancy test is negative and I take half of a Thyronorm 125mcg tablet daily for an underactive thyroid, and what should I do next?
It is completely understandable to feel anxious, but please be reassured that minor cycle delays are very common. Since you take Thyronorm (levothyroxine) for your thyroid, even slight fluctuations in your hormone levels can delay your period and cause symptoms like feeling hot, mood changes, and nausea. Stress and anxiety can also contribute to this delay. Since your pregnancy test was negative, your symptoms may just be PMS. I recommend waiting another 2 to 3 days and repeating the home pregnancy test with your first morning urine. If it remains negative and your period still hasn't started, please consult your doctor to check your thyroid levels.
