I was in the same situation back in 2006 pregnant with my first child. I requested to do triage and office duties and injections instead. I was very fearful and looking back I may have slightly overreacted but one never knows. I do feel you have the right to have the pregnancy you want and certainly have the right to demand a safe environment for your baby. At this point you are almost done with your first trimester which is the most dangerous part to be around chemotherapy. After the first trimester, chemo can even be administered to pregnant patients. So, looking at it that way you probably don't have much to worry about at this point. I understand your feelings, it was a very difficult situation for me to decide on since they pretty much wanted to fire me for not being able to do the job they hired me to do and I always felt I was letting them down by not doing it. But, it is your first act as a mom....sometimes you have to make difficult decisions that aren't always clear. I think no matter what you decide you won't regret your decision. If they will willingly give you another job for the mean time then go for it, but if not, you probably will be okay. Consider breast feeding too...if you plan to do that you have to consider chemo getting into your milk supply as well. Just a thought. Congrats and best wishes!
