How do birth control pills affect thyroid hormone levels?

Hi everyone 😛
About a year ago, I was diagnosed with latent hypothyroidism: my TSH levels were elevated, though my T3 and T4 remained within the normal range, and an ultrasound confirmed chronic thyroiditis.
I haven't started any medication yet, but I have a follow-up appointment scheduled with my endocrinologist in about a month. Interestingly, my weight is actually below the healthy range, which feels a bit off since I've always heard that weight gain is the standard symptom associated with hypothyroidism 😂
Before this checkup, I’m planning to get my thyroid hormone levels tested again, but since I’ve been on Diane for five months now, I can't help but wonder if my results might be skewed... I know these hormones tend to influence one another. Is it possible for my birth control to interfere with the readings, and if so, how long would I need to stop taking Diane to ensure my thyroid values are accurate?
Thanks in advance 🙂

It’s definitely possible. My endocrinologist actually asked me if I was on birth control when we were checking my thyroid levels.

Honestly, you should just run it by your own doctor to be safe.

So, how much time actually needs to pass between taking the last pill and getting blood work done for hormones? Does anyone here happen to know the specific window...😛
