McDonalds obsessed

Hi. I need someone to make me feel better! lol I am 5 weeks pregnant and dealing with quite a bit of nausea. when I first found out I was pregnant, I promised myself that I was going to eat healthy. but now, all I can stomach is french fries and chicken nuggets from McDonald’s. Why? I have no freaking idea. I didn’t even really like McDonald’s before I was pregnant. everyone talks about how the first trimester is so important and all I feel like I can eat is french fries and chicken nuggets. 🤣 i’m taking my prenatals and getting plenty of sleep, but I am definitely discouraged about my diet, but I seriously don’t think I could keep down anything healthy right now.
