Im pregnant (9 weeks) and i feel like i have the flu. i'm a bit warm like a fever was coming on so i took tylenol (acetaminophen). should i go to the hospital?

Doubtful: Treat with fluids, rest and Tylenol (acetaminophen). If you develop abdominal cramps, fever or urinary symptoms I would go then. Simply having a viral infection is not a risk to your pregnancy. Spotting/cramping could be threatened miscarriage and fever with urinary symptoms and/or flank and pain could be kidney infection. Infections of urinary tract increase risk of miscarriage ,
