Congrats sa 14 weeks, mama! Positive nitrite usually does mean UTI, kaya importante talaga na i-address mo ito with your OB sa June visit, don't wait kung mayroon kang symptoms like burning pag pipis or frequent urination, okay? A few of us moms had UTI during pregnancy din and honestly, once na namedicate properly, it cleared up fine, the doctors are really careful with antibiotics na safe for baby, so don't worry. Sana mabilis lang ma-confirm at ma-treat ninyo, at congratulations ulit on your little one, napakaganda talaga makita sila as a fetus na!
