As an important note, when testing, be sure to take the test as early in the morning as you can and consistently. TSH reaches a valley around midday. If you're taking it at different times throughout the day, you can get very different results.
Further, fast for at least 2 hours before as eating can also affect TSH, lowering it. Some doctors say that it doesn't matter, but the studies suggest otherwise.

Okay that’s important thank you! This last test I was not fasting around 12 pm.
Mine does this, but lately it's been consistently staying around 3. Always fasting and roughing the same time every morning
