Can someone help?

Cindy

So I got my Mireia Dec 14, my bf went out of town for the holidays so we used the pull out method (stupid I know) before he left. We waited another 2 weeks and he finally came inside me. My questions is I’m okay right no chance or being baby momma number 2 ? I’m just freaking out cause I never had the hormone iud only copper & im late so I don’t know what to expect
