Fainted at chuckie cheese

Im 13 weeks pregnant and I brought my kids to chuckie cheese today and I got really dizzy and everything went black then next thing u no I'm waking up on the floor with my husband over me worried out of his mind ever since then my feet keep falling asleep here and there but I don't feel bad a little short of breath but my oldest daughter wants me to go to the hospital she's worried I keep telling her I feel fine but now I feel she may be right what should I do and should I be worried
