Husband is sick. Chills cough fatigue no fever it seems like no aches. Took flu test on first day and was negative. I am almost 20weeks and I am terrified of the flu do u think he has it or no. So scared. I can’t take Tylenol for fever I am allergic what would I do? So scared. Any advice. Can’t stay away we thought since negative it was fine but then today he feels worse even with chills.
