Flu during pregnancy

I’m in the ER they told me I have the flu 😢😢😢 I cant stop crying. I really don’t want to take any medication I’m so upset. They gave me a breathing treatment and the sodium chloride and I was panicking about that now they come back and tell me I have the flu and they are giving me tamaflu? Help me please anyone had the flu before and their babies are okay? I’m freaking out!

I am 28 weeks I forgot to add that
