Girls, hello. 37 weeks pregnant, on Monday I'm going to the maternity hospital (diagnosis GSD). For three days now the temperature is 37.1 and there's body aches. There are no symptoms of a cold. Today my head is splitting! ?‍♀️ Why is that? I read that it's one of the precursors, is that true? I won't go to the doctor, most likely I will call her.
