Ay, congrats on your pregnancy, mama! Hindi ako naka-Duphaston at Duvadilan combo kasi iba ang case ko, pero a few of my mum friends were on similar meds during their pregnancies at okay naman sila, ang importante talaga is follow mo exactly kung ano prescribed ng OB mo kasi alam niya ang specific reason bakit kailangan mo ng meds na yan. Definitely okay lang mag-check in with your doctor if may side effects ka or worried ka sa something, pero generally yung mga meds na yan prescribed lang talaga during pregnancy para i-support ang pregnancy natin, so wag mag-alala too much. Hang in there, first-time mama!
