Aiyah memang common lah ni sis, a few of my mum friends went through the same thing dalam 3rd trimester, the nausea and aversion to "proper" food tu legit, bukan dalam your head je. Honestly, if you can keep down the junk food and you're making up for it with fruits, kurma, and kismis, that's actually better than forcing rice down and throwing it all up lah, at least something stays in your system. Tapi the tiredness + hunger combo ni tak okay, so maybe talk to your doctor about it, especially since you're working, to check if ada anything else going on or if you need specific supplements. One thing I noticed with my pregnant friends, sometimes when nasi really tak boleh, they'd try other carbs like roti, pasta, or even oat cereal yang easier on the stomach. Don't stress yourself terlalu banyak about the burgers occasionally lah; baby tu tough and akan ambil what she needs first from your body
