Confused

So my mother told me using toys during you most fertile days can hurt you more than helping while you TTC. We are really close and I’m grown lol so I’m very comfortable with talking to my mother about anything. Anyways lol, so now I’m like not sure if she just messing with or helping me. She is think using any toys and thing in that nature is nasty and I should pray more. Lol she is very old school. So I want to is true or not about toys.
