Uy mama, 38 weeks pa lang, please talaga consult your OB muna bago mag-try ng kahit ano, ha! They need to check kung ready na ang baby at ang body mo, especially since second baby ka na. A few of us moms have asked the same thing, pero honestly ang doctor ang dapat mag-guide sa inyo on what's safe sa stage mo ngayon. Every pregnancy is different, lalo na pag second baby na. Just follow your doctor's advice and trust the timing, your baby will come when baby is ready. Kaya mo yan!
