Bad for implantation?

I don't know if it will stop it, but they say that if you're implantation is happening, your uterus will be more sensitive and the c will be more sensitive to foreign objects. Like, I've read that if you think you're having implantation bleeding, not to wear a tampon, but a pad instead, but I don't think it would stop the process. Otherwise, all the sites and doctors would tell you that you can only have the days between the start of your AF and the day of ovulation.
