Mama, better pa rin to have it checked with your OB just to be safe, especially since you're in early pregnancy, kahit minor lang ang cough, gusto mo peace of mind na walang underlying issue, di ba? A few of us tried self-medicating during pregnancy pero mas comfortable kami pagkatapos ng check-up kasi alam namin okay lang ang gamot for baby, so go na lang to your doctor para sure at ma-prescribe ka ng pregnancy-safe remedy if needed.
