Thanks Babysmurf and Amlikam for the balanced perspectives and recommendations! Very valuable input.
SweetMama--- ultimately you choose what's right for you, your medical history, your beliefs and family. I can only tell you the decisions I would make today given my personal experiences and my personal fears. I certainly have great faith in homeopathic medicine and in alternative approaches --- however, having been hospitalized with the (real deal) flu in the past, I personally would go to great lengths to avoid a full blown case... pregnant or not. I was in my early 20s, had been vaccinated, and was very active and fit when I got the flu, yet I required supplemental oxygen and fluids at the hospital and it took me months to recover fully. Additionally, in my case, it was only a matter of hours before I went from feeling totally fine to being as sick as a dog, so (for me) I doubt that probiotics would have had enough time to put up a good fight. : /
Only you can judge how you're feeling now and weigh the risks and concerns you have. I fully support your decision to not take the Tamiflu if you think it's overkill or not quite right, and don't let my personal story push you in a direction you're not entirely comfy with.
Lastly, I think perhaps my first response was perhaps (due to my own experience with the flu) a bit knee-jerk and my recommendations for hospital/intervention came across as too strong (which is yet another reason I'm thankful for Babysmurf's comment). High fever and flu or flu-like viruses should be taken very seriously, but if you can play an active role in keeping your symptoms in control, that's really really ideal. If your temperature is staying stable and you can keep it in check with Tylenol, liquids, and baths, I think that's a very good sign.
In addition to comments here or elsewhere, you might find this write-up by the March of Dimes on pregnancy and flu as a valuable resource to advise your actions:
