Ay, congrats sa 37 weeks, mama! Para sa specific details about Hospital ng Maynila's OPD schedule and holiday operations, best call them directly na lang, kaya nila sagutin agad at confirmed ang info para sa iyo. A few of us mommies always ring ahead talaga, lalo na with holidays, para sure na wala hassle pag dating mo. Fingers crossed makakuha ka ng slot! Keep safe, sis!
