Ah mamsh, that's a really good question! Para sa anumang herbal oils or supplements during pregnancy, best talaga na tanungin mo muna ang OB mo, kasi iba-iba ang pregnancy journey ng bawat mama at some things need professional checking. A few of my mum friends were really careful din sa lahat ng ginagamit nila during pregnancy, better safe than sorry, di ba? Your doctor will know what's safe for you and baby.
