Is it safe to eat cup noodles?

I’m 11 weeks now and have been experiencing very bad nausea ever since I found out I was pregnant. My appetite was so bad that I could only stomach certain kinds of food that are mild tasting and “safe”. I can’t eat too much at one go too, I will feel very sick. So I get hungry every 1-3hrs. Sometimes I even get hungry 15mins after a meal. There is one food that I will always crave and can manage to finish the portion. That is my favourite cup noodle. So far I’ve been eating it 1-2 times a week. I know I’m not supposed to as per reading online, but sometimes I get so hungry and crave for that. I will ask my gynae when I see her next week. But I’m just wondering if any of you guys have the same cravings and how much of instant noodle do you eat.
