Unlikely, but certainly not impossible. Test at like 2 weeks past the time. Then if it does happen to be positive, make an apt immediately. As Dionna said, risk of ectopic is higher with IUD.
I got pregnant with an IUD and it turned out to be an ectopic pregnancy. IUDs fail more than you’d think! It never hurts to take a test to have peace of mind, but maybe wait another week or so!! Or buy a pack of two and do one now and one in another week
probably not
My sibling fell pregnant with that thing and I've known a good number of others it's happened to. I'd test in two weeks from when you had sex and see just to be safe, especially if you know you're pretty fertile I feel like better safe than sorry ☺️ also you can have it checked by your provider if you don't know how yourself
