Super nauseous/sick in the morning but starving by lunch time?

I’m 8+4, and have struggled with nausea/morning sickness since 6 weeks. I feel so nauseous in the morning, and I’ve thrown up several times but by lunch time I’m absolutely STARVING and if I don’t get what I’m craving at that moment I feel like my stomach is gonna eat itself 😭 does anyone else feel this way?? I’m a FTM and literally have no idea of what’s normal.
