Hey, for anything na parang ganitong tanong about what's safe to use during pregnancy, mas better talaga na tanungin mo directly ang doctor mo or OB mo, they know your pregnancy best, ika'y, at pwede nila i-check if it's okay for you specifically. I know marami sa atin gumagamit ng iba't ibang oils para sa comfort, pero pregnancy is really a time na kailangan ng professional advice lang talaga. Mas peace of mind para sa iyo at sa baby, di ba? Tawagan mo nalang clinic mo or visit kapag may chance ka, they're used to these kinds of questions!
