Hi mama! Okay lang naman usually ang Myra E while on pills, pero since it's about supplements and contraceptives together, best to double-check with your OB or doctor para sure, kasi bawat tao different ang body chemistry nila, especially if may ibang meds or conditions ka pa. One of my friends asked her doc din about vitamins while on pills at sabi okay lang, pero better safe than sorry talaga! Don't worry, moms here got you.
