Scared

Guys I’m so scared, so I was sporting a week ago and I took it that it was my period. (I AM ON THE HORMONAL IMPLANT) so this could’ve just been random spotting but I was cramping so I took as my period. In the second to last day I had unprotected sex. My boyfriend and I have been having unprotected sex for awhile now. But I have had the iud for over 3 months. Anyways I’ve been cramping lately, like stomache or period cramps but no spotting or bleeding. I just started heavily working out the past two weeks(when I was spotting) so maybe that could be the cause of this idk? Either way I’m nervous. My app shows that I should be ovulating right now and it says that on the day I had sex I had a high chance of becoming pregnant but I’m not sure how accurate that is. Anyways it has been 6 days since unprotected sex. I may just be overthinking it but I am really nervouse I could be, is this just symptoms of the hormonal IUD?
