Mama, these are really important questions, please talk to your OB-GYN as soon as possible, especially about the UTI kasi yan ay kailangan ng proper check-up at treatment para sa baby mo. For the vaccine, your doctor can best advise kung ano ang safe para sa inyo ngayon based sa kung saan ka na sa pregnancy. A few of my mum friends had different experiences depende sa trimester nila, so talaga dapat i-discuss mo ito with your OB directly, they'll know what's best para sa iyo. Take care!
