Congrats sa kasal at baby! Honestly, you can update after you give birth na lang, marami sa amin ginawa yan para hindi na stressful habang pregnant, lalo na with your bleeding concerns. The important thing is your PhilHealth is active (kahit old name pa) because kailangan mo siya for hospital bills, and SSS benefits usually follow through na even if your name hasn't been updated yet, pero check with SSS directly kung may pending claims ka just to be safe. Travel naman tatlong oras is really risky given your situation, so I'd say take it easy muna and do the name change updates after November when you're recovered, your health and baby's safety comes first, lagi yan priority natin. Your ob is right to restrict you from long travel, so listen to her.
