Mamsh, I understand ang concern mo, UTI during pregnancy is really tricky talaga, especially pag limited ang antibiotic options! Honestly, probiotic alone for UTI ay di ko pa nakita na full-on treatment sa friends ko, kaya I'd really encourage you to follow up with your OB and maybe ask directly kung ito lang talaga ang plan or may steps after the 10 days, because UTIs sa third trimester can be serious pati baby. A few of us had UTIs during pregnancy and most were given antibiotics na pregnancy-safe (like amoxicillin or cephalexin), so it might be worth clarifying with your doctor if there's another option, or if the probiotics ay support lang while waiting for something else, either way, don't hesitate to call her clinic if symptoms get worse or don't improve after the course. Sending you healing, mamsh!
