When it comes to concerns about delayed periods, especially in the context of recent sexual activity and thyroid issues, it's important to consider several factors that could be influencing your situation.
First, let's address the possibility of pregnancy. You mentioned that you and your boyfriend have been using full protection during intercourse. If you have been diligent in using effective contraception, the likelihood of pregnancy is reduced, but not entirely eliminated. Condoms, while effective, can sometimes fail due to breakage or slippage. If you are concerned about the possibility of pregnancy, the most straightforward way to confirm or rule it out is to take a home pregnancy test. These tests are generally reliable and can detect pregnancy hormones in your urine as early as the first day of your missed period.

Now, regarding your thyroid issues, hypothyroidism (low thyroid function) can indeed affect your menstrual cycle. The thyroid gland plays a crucial role in regulating various bodily functions, including metabolism and hormonal balance. When thyroid hormone levels are low, it can lead to irregularities in your menstrual cycle, including delayed periods or even missed periods altogether. If you have recently started medication for your thyroid condition, it may take some time for your body to adjust to the new hormone levels, which could also contribute to changes in your menstrual cycle.

In your case, since your period is already six days late, it is advisable to take a pregnancy test to rule out pregnancy as a cause of the delay. If the test is negative and your period does not arrive soon, it would be wise to consult with your healthcare provider. They can evaluate your thyroid function through blood tests and assess whether your current medication is appropriate or if adjustments are needed.

Additionally, stress can also play a significant role in menstrual irregularities. If you are feeling anxious about the possibility of pregnancy or your thyroid condition, this stress could further impact your cycle. It’s essential to manage stress through relaxation techniques, exercise, or talking to someone about your concerns.

In summary, while pregnancy is a possibility that should be ruled out with a test, your thyroid condition could also be a significant factor in your delayed period. Monitoring your symptoms and maintaining open communication with your healthcare provider will be crucial in managing both your thyroid health and menstrual cycle. If you have any further concerns or if your symptoms worsen, do not hesitate to seek medical advice.
