Is it safe to use devices like microwave, cellphone, laptop when pregnant? Do I need to be worried about the radio frequency waves?

I don't think it's something to be worried about. Everywhere we go, you'll see mobile phones, computers, etc. If you are really paranoid about radio frequency, are you not going to use your phone and avoid computers thorough your pregnancy? I work with both computers and phones during my pregnancy and occasionally use the microwave to reheat my food and alhamdullilah, my baby is healthy
