Influenza B and pregnant

Ladies

Went to the ER yesterday bc I has slipped and fell on my butt. And I started to cramp pretty good. Waited awhile b4 I went to see if I could get cramps to calm down, laid on left side drank water nothing worked so went to the ER.

Did UA looked ok but still going to culture it

Did Flu test and came back positive, yay me. My 7 yr old daughter had it first (maybe) and gave it to the rest of us.

Er dr gave me a liter of fluids, and that didnt help cramping either. Still have cramping. She called my OB and he said tylenol 1000mg 3x a day and then 400mg of ibuprofen if tylenol didnt work. And to call him in the am (which is now) and make an appt if cramping didnt stop. Prescribed Tamiflu and want me to take it. 13w4d.

Chest hurts bad cramping still there and have headache from hell.

I have 3 kids here at home do you think they will admit me?
