Mama, yan talaga common sa first trimester, the hormones plus Duphaston can make you constipated, and yung dilaw na wiwi could be related sa pregnancy hormones or diet rin, pero with the subchorionic hemorrhage you have, kailangan mo talagang check with your OB about this instead of guessing lang, para sure na okay lang both you and baby. Folic acid and Duphaston side effects normally include constipation, nausea, at slight dizziness, pero yung combination mo with the bleeding is something your doctor needs to monitor closely, they might adjust your meds or add stool softener para makatulong. Laban, mama!
