Hmm, I get why you switched kasi ang mahal ng mineral water dito talaga, pero honestly better to check with your OB about this one para sure, distilled water is super stripped of minerals, at habang pregnant ka dapat makakuha ka ng enough electrolytes and minerals para sa baby at sa'yo rin. Maybe ask your doctor kung okay lang sya or if there's a safer option na affordable, or if you can mix it with something? Ang aking doc before kasi sinabi na okay ang purified water but not consistently distilled lang, so better safe than sorry talaga when you're 7 months na!
