I ve had a low grade fever since the weekend. And, the only symptoms I ve had is an on and off congested nose. I just found out I was pregnant (today = 5 wks, 6 days). I saw my OB yesterday and he said it sounded like an upper respiratory (virus). I m just really concerned about the fever and the development of my baby. This is our 2nd, planned, pregnancy. Any words of advice?
