Mommy, please call your OB or go to the nearest hospital right now, kahit brief exposure lang, it's better to get checked and have peace of mind, lalo na kang pregnant.
A few of us mums have had similar scares (accidental fumes, smoke, etc.) and honestly, ang best thing talaga is to get the doctor's reassurance in person, hindi lang peace of mind, kundi they can check you and baby properly. Don't worry yourself too much habang nag-aantay, pero priority talaga ang checkup. You're 17 weeks, ang baby mo may good chance, pero kailangan mo ng medical eyes lang, not just guesses from us moms. Let me know how it goes, okay?
