Hello. I'm 9 weeks pregnant. I had an ultrasound, they said there was a threat. Now, for the past two days, I have slight fever-like symptoms, but my condition is terrible: my throat hurts, my nose is stuffy, my bones all turn, and in the evening I feel bad overall. I've been nervous for a week. What should I do?
