Terrible morning sickness

Today I’m 8 weeks, 3 days. My morning sickness kicked in at 6 weeks and 5 days. Now I constantly have a headache. On a norm, I suffer from migraine and now it seems like it’s a migraine x 10. Not only am I nauseas because I’m pregnant but also because of my headaches. I’ve lost 5 pounds since I found out I’m pregnant because I can’t retain any food. 😩😩 don’t know what to do. All the doctor say is try to eat. 🤦🏽‍♀️
