Pregnant and prescribed Tamiflu?

I am five to six weeks pregnant right now. My stepson who spent the night on Saturday woke up on Sunday incredibly ill and it turns out he tested positive for swine flu. He was only at my house from 9 at night to 9 in the morning and my husband sprayed Lysol on every thing in the entire house just in case. Today I called my doctor and explained the situation and she called in a prescription of Tamiflu to my pharmacy. She said she wasn't sure of the side effects on pregnant women but that the risk of swine flu would be worse for the the baby. But I'm not feeling sick at all... besides the normal pregnancy symptoms. However I am aware that I may not have gotten it this time, but who knows what could happen in the next few months. So my question is- what would YOU do if you were in this situation? I have been trying to get pregnant for well over five years. This baby is everything to me and I just don't know what to do. My husband says I shouldn't take the pills if I'm not sick and just wear a surgical mask in public from now on, and my father says it's better to risk it with the pills then to get the flu and the baby die for sure. I'm just so confused.
