Uy mama, I'm so sorry you're going through this. Please go to your doctor or emergency room right now, ang white discharge kasama ng severe back and pelvic pain after miscarriage ay kailangan ng immediate check-up, hindi ito dapat palampasin. A few of us mums have been through this, at ang aming doctors always said na after a loss, any unusual symptoms need proper medical attention agad. Huwag maghintay pa, okay? Take care of yourself.
