Girls, hello, has anyone had a cold during my due date? I'm having an ultrasound tomorrow, exactly 12 weeks. For two days now I have a stuffy nose and weakness, and even vomiting that I don't drink or eat anything outside!((( I went to the doctor, he prescribed Oseltamivir-Acivir drops for the nose and ascorbic acid. Lots of drinking and more rest. I'm worried about the baby, I keep coughing all the time, thank God there is no phlegm. Because of the worries I want to cry, that I do ?
