anyone fell very sick while pregnant?

Fell sick with the flu at about 19 weeks pregnant. Had cough, runny nose, sore throat and fever. Went to GP and they prescribed me piriton, difflam gargle and panadol. My fever was on and off so had to take Panadol when I had high fever. One of the night I woke up shivering with high temp. Went to KK at 2am. They monitored me, gave me IV drip. At 6am fever was still above 38 and they said my heart rate was elevated. So got admitted for monitoring. My fever kept coming on and off for next 2 days. 3rd day discharged with no fever but still having cough. I lost my voice on the first day at the hospital and had a raspy voice for over a week! Honestly, it was my worst common flu experience ever! Being pregnant was super worrying but baby thankfully was fine. Was Covid negative and whatever infection negative. They just said it’s the common flu. I’d say it took me 2 and half weeks to fully recover since first symptom. My advice, see doctor. Best to go to your gynae as they know the pregnancy safe medication. I was getting mixed info as my GP said I cannot have lozenges but at KK they said can. Also, yes limiting your medication is best, so take when really required. Other than that try eating healthy and drinking lots of water to bring back the immunity! Body will fight the virus!
