What should I do

Hey ladies, I had my last period on Oct 17th I had sex on November 3-5 according to glow I was ovulating on November 4-5. When I looked online to other due date calendars it said October 31-November 2nd I didn’t log those days so I can’t remember if we did it then or not. I go later today to get a mirena put in. My question is should I test before I go even though my next period isn’t for another 15 days? I would hate to get it put in so close to my ovulation dates and wind up pregnant with it in. Please help!!!
