8 weeks pregnant ... nauseous

Need advice please! This is my first pregnancy and I think I'm 8 weeks pregnant now , got my first scan this Friday. I've been feeling very nauseous for the past two weeks. I've literally been stuck in bed and I just started vomiting yesterday morning and night. Is it going to get worse? How long is this going to last for? Is there anything I can take/do to feel better? This is my first pregnancy and I wanna feel happy and good about it but I've just been feeling horrible lately. ☹️
