Anak, this is really something you need to talk to your OB about right away, hindi ito dapat i-manage on your own, whether you're pregnant or not. Cervix concerns need proper medical check-up kasi maraming possible reasons, and what's safe depends entirely sa situation mo.
Please go see your doctor or go to the nearest clinic/hospital, ha? I know it's scary to ask online, but this one really needs a professional. Sending you love, take care of yourself.
