Ay, mama, I'd really suggest checking with your OB muna before continuing anything, kahit vitamins na ginagamit mo before, better safe than sorry talaga when you're pregnant, diba? A few of us mums learned the hard way na what worked for us before pregnancy might need adjustment, especially with nightshift stress mo. Your doctor can recommend what's actually safe for baby at para sa energy mo while working nights. Don't worry, they'll give you better options na specifically okay for pregnancy!
