Progesterone and crazy morning sickness

Hey friends. My progesterone is at 8.5 and my doctor has me on progesterone every day but I’m still nervous! How low is too low? Also I’m sicker then I’ve ever been. How am i suppose to continue a normal life AND keep it from people when I feel like this! My husband is not understanding and expects me to function normally but at this point it looks like I will be in bed for the full 9 months
