Huhu alam ko yan girl, sobrang frustrating talaga pag ganyan, three months na, that's really tough and stressful talaga. Alam ko may few of us mums na nagka-UTI din after delivery or catheter, pero honestly the recurrent ones like yours need proper medical attention kasi pwede may underlying issue pa that needs different treatment, hindi lang antibiotics ulit. Since nag-checkup ka na ng tatlong times, maybe it's time to ask your OB or urologist kung may other tests na kailangan (like ultrasound ng urinary tract) or kung kailangan mag-refer ka pa, because repeated UTIs can mean something else is going on na hindi pa identified. In the meantime, drink lots of water, try to pee after intimacy, at make sure you're hydrating well especially if breastfeeding pa rin. Sending you virtual hugs, alam ko nakakabagal pero you'll get through this!
