No period No clue?

So I just got a new iud last month and my period is coming up and I was told my period could disappear. I loved my periods only for the comfort of knowing I wasn’t pregnant. Should I buy a pack of pregnancy tests to give myself comfort Incase my period doesn’t show? How do you cope with not having a 100% That you aren’t pregnant. My boyfriend and I have been using condoms for this month but we like to go bare and use the pullout once we know that the IUD is set
