Ay nak, this is something you really need to ask your doctor or go to a clinic about, timing ng pills is super important para effective talaga, at depende sa brand mo and kung kailan mo dapat i-start. One of my mum friends almost made the same mistake, and thank goodness she texted her OB muna! Different pills have different schedules, kaya better safe than sorry. Give your doctor a quick call or drop by a clinic, they'll tell you exactly kung kelan mo dapat magsimula. Mas maayos na peace of mind, diba?
