Ay mama, congrats sa 31 weeks na! Honestly, yung schedule na yan ay dapat tanungin mo talaga sa OB mo next visit kasi iba-iba ang protocol ng bawat hospital, some start weekly checkups at 36 weeks, pero may iba nang mas maaga. Best to ask your doctor directly para sure, at pwede ring i-discuss with them kung paano mo ma-manage kung kailangan mong magpunta ng frequent while your hubby's working. One of my mum friends din had similar concerns, at nag-arrange lang sila ng transportation plan with her mom para sa peace of mind, maybe that's something you can think about din in the meantime?
