Sayang, this is something you really kena check with doctor or clinician, okay? Double line even if samar-samar usually means positive, tapi bleeding at the same time boleh be different situations, some mums I know went through this and turned out okay, some kena monitor closely. Don't guess-guess lah, go see your doctor ASAP so they can do proper test and make sure you and baby are okay. Better safe than sorry!
