Ay sis, karamihan sa amin na preggy talaga prone sa UTI kaya hindi ka nag-iisa! A few of us went through the same 7-day antibiotic course around 6 months din, at talagang kailangan tapusin lahat ng gamot even if you feel better, importante yan para hindi bumalik. What really helped most moms I know is drink lots of water, like 2.5-3 liters daily, pee every 2-3 hours (and always after, um, activities), and palit ng cotton underwear, sounds simple pero sobrang effective talaga para sa hirap na yan. Iwasan din salty foods and stay hydrated, plus front-to-back lang always. Pero definitely confirm with your OB kung may karagdagang concerns ka or if the symptoms don't improve after you finish the meds, kasi bawat pregnancy is different and she knows your case best! Kaya mo yan mama, pass din 'yan!
