Uy, this is really something you need to ask your OB or pharmacist directly, mamsh, switching between pill brands can be tricky and it depends on your specific situation! Alam ko nakakaconfusing ang ganyan, pero they'll give you the exact timeline na safe for you. A few of us mums ask our doctors before we switch kasi bawat body ay iba, and they always appreciate the question. Get in touch with your OB soon so you know exactly what to do, okay?
