I'm so sick today

He
I'm 11w3d today and I've never been so sick. I haven't been able to keep anything down except some milk since last night. My head hurts and I'm so hungry right now but I'm tired of puking. I even tried toast this morning and it came up too. I have been in bed all day. I don't know how I'm going to make it at work tomorrow with a 10 hour shift.
