Hey mama! Brown discharge while on birth control pills is usually normal, it's often just old blood, especially in the first few months habang nag-aadapt ang body mo sa hormones, pero since it's a health concern na specific sa iyo, mas better talaga magcheck lang with your OB para ma-ease your mind, okay? Altea is good skincare but it won't affect your BC pills naman. Hope maayos lang lahat for you!
