Pwede po bang itake ng Althea kahit hindi pa nireregla? I do have a PCOS po, don't know what to do.

Are you taking meds for your PCOS? If you are, talk to your ob if you still need another birth control kasi syempre the combination of medicines in your body can lead to different side effects. If not, it's still best to talk to your ob first para ma-guide ka kung anong medication/ contraceptive method ang tama para sa'yo.
