Ay, this is such an important question kasi talaga, certain contraceptives can affect thyroid levels! Best talaga na isang tung-tung kang magtanong sa your ObGyne directly, kasi iba-iba ang situation ng bawat mama, some of my mum friends with thyroid issues were advised to avoid hormonal options and went with IUD or barrier methods instead, pero really depends on your specific thyroid levels and kung stabilized ka na or not. Dapat rin consistent ang thyroid monitoring mo habang nag-try ng any contraceptive, kaya important talaga yung communication with your doctor about this!
