PLEASE HELP

lila

So I have had an IUD for 2 years, and obviously me and my boyfriend have sex but sometimes we start having sex without a condom but like halfway through he will put one on and pull out with it when he finishes. My period is late, and I am freaking out I don’t even have cramps. Am I pregnant? I recently started going to the gym three times a week and I’ve been stressing about my period I don’t know what to do please help me
