Cats and pregnancy.

I just found out I was pregnant, and have a questions regarding cats. I have two Sphynx' who are like my children. My male cat is stuck to me like glue, and will not sleep anywhere else but directly on me (sometimes on my face he he.) I was doing my research about toxoplasmosis, and was wondering what everyone's thoughts were regarding cats and pregnancy. I know that I am off cat litter duty for the next 9 months, however, I was wondering what boundaries I should or am required to make regarding my cat sleeping with me. 

My sister in law suggested that he should not be allowed in the bedroom anymore, and should certainly not sleep with me. My two cats are indoor cats, and never go outside. They are also furless (Sphynx.) It would be so tough for me to cease sleeping with him. I am just wondering what my fellow "cat ladies" think about all of this?
