Ay nako, ganyan talaga ang UTI during pregnancy, nakaka-stress talaga lalo na malapit na! I had recurrent UTIs din with my second pregnancy around that time, and honestly the bedrest + antibiotics combo worked, baby came out perfectly fine at healthy pa despite all the scares. Your OB is right na kailangan i-take seriously ngayong stage, but maraming mums I know have been through the same at lahat nag-deliver normally, so try not to worry too much (easier said than done, I know!). Make sure din you're drinking lots of water, cranberry juice if kaya mo, at complete the full course ng antibiotics talaga, a few of us actually made the mistake of stopping early thinking we're fine na, tapos bumalik pa. Sending you all the good vibes, mommy, almost there na kayo!
