Almost 8 weeks.. and whole house is sick

Ta

I’m 7 weeks and 5 days today.. felt ok this morning but progressively felt worse as the day went on. I haven’t had any morning sickness, nausea here and there. My sister who live with me went home sick throwing up and diarrhea. I got home from work and been throwing up all night and can’t keep anything down. Stomach cramped and have diarrhea. Any suggestion? I feel terrible, currently sitting on the bathroom floor crying.
