has anyone or something you know gotten pregnant on the IUD?

I'm on Paraguard, and I am concerned about being pregnant. I still take my temps to track when I ovulate, just for the future. And my temps have been very high this month. Not a normal dip that I get at 5 dpo, it's weird. I don't know what do you ladies think? And no im not trying to get pregnant I just like to track to see where I am and when I can expect my period.
