Anyone take Tamiflu while pregnant

I'm really scared and I'm hoping that someone can put my mind to ease. 
I'm 17 weeks pregnant and my husband and toddler were just tested positive with Influenza type A (Flu) 
I feel like I am now coming down with it and My OB wants to put me on tamiflu as a preventive measure. Does anyone have information on Tamiflu and pregnancy or has anyone personally taken it? 
Any response is much appreciated
