What Are Effects Of Taking Birth Control While On Thyroid Medications?

Hi! I'm on synthroid (0.05mg) for my hypothyroidism and would like to go back on the pill. I've only been on my thyroid meds for about a year and a half and haven't been on the pill since I started. Are there any repercutions to taking birth control (or a certain brand of bc) while being on thyroid meds.
