Uy, vitamin at supplement questions talaga kailangan i-check with your doctor ha, especially ngayong nag-take ka ng ganitong meds, they might interact, at basta pre-term labor concerns mo, mas importante pa na follow-up lang siya agad. A few of us mums nag-share before na what worked for one person ay not the same sa iba, lalo na sa ganyan serious situation mo. Better safe talaga na tanungin mo doctor kung pwede pa ba dagdagan or share yung extra mo sa ibang mama who needs it, pero huwag mag-self-medicate na lang. Sending you strength, mama!
