Daughter is sick puking while I'm pregnant

Ladies I am almost 27 weeks pregnant. My 6 year old just threw up for the first time this morning. Partially on the floor and on my foot. I am extremely worried about getting this. I was just sick with a stomach bug and puking not even a whole year ago. My daughter only got an upset stomach with diarrhea maybe twice. She was hardly phased. I later ended up being sick a whole night puking pretty consistently every half hour to an hour. By the last time I threw up I knew if i had to puke again I was going to black out because I had no more energy and nothing left inside me. It was horrible and I wasn't even pregnant. I am so scared to go through that again while pregnant. What can I do? Any advice? I don't want the baby to get hurt or end up in the hospital.
