Can you become infertile due to radioactive waves from a laptop?

I'm only 14 but I already have my life planned out. That life does include kids but my friend told me that you can become infertile if you do things such as have a laptop on your lap or put your mobile phones in your bra and stuff like that due to radioactive waves. I'm really scared because since I was 10, I have been using a laptop every night just to go on facebook and it is always on my lap so I want to know if this is true! Please answer if you are a doctor because I am really scared.
