Get new lubricants.
Some lubricants specifically contain spermicide, but even lubes without spermicide might hurt your chances of conceiving. Sperm doesn't survive well in water-based lubricants (that includes saliva). If you still want to use lube but don't want it interfering with conception, there are special products you can buy. Dr. Thomas J. Walsh says you can also use household products, like vegetable oil or eggs whites. (Although he adds that he's never had any takers regarding egg whites.)
