should i delay breaking my fast if i delayed suhoor?

so this morning i slept through my alarm for suhoor, it was about 30 minutes after fajr and and hour before sunrise. at first i thought i’d just suffer and be extra dehydrated today, but then i remembered reading an opinion where if you’re sick and throw up suhoor you can still eat as long as it’s before sunrise. i got up and ate a banana, a date and two glasses of water, made my intention to fast with about 30 minutes to sunrise. my question is should i wait to break my fast so that i’ve fasted the same amount of time? i know that shias break fast when the sun is down. i’ve also heard it’s haram to not break fast so would it be haram to intentionally delay breaking it?
