Hey mama! Yan ay totally normal naman, lalo na pag may increased discharge ka sa pregnancy, maraming doctors ang nag-order ng swab or culture para ma-check lang if may infection like yeast or bacterial vaginosis, especially pag may unusual color o smell. A few of us moms had it done din around that stage, kasi better safe than sorry talaga pagmalapit na ang delivery! I'd say go ahead lang with the test kung recommended ng OB mo, it's just a quick swab and peace of mind lang yan para sa iyo at sa baby.
