Uy, this is really important, hyperthyroidism + birth control is something you really need to discuss with your OB or endocrinologist, hindi lang kami moms ang makakasagot dito. They need to check kung paano mag-i-interact ang meds mo with any pill you choose, kaya please set up an appointment agad if you haven't. A few of my mum friends with thyroid issues din went through the same concern, and each one had different options depende sa severity ng condition nila, so it's really personalized. Huwag mag-start ng anumang pills without clearance, ha. Seryoso ito.
