random spotting?

Hi guys. im not sure what group ti post this in. I got my kyleena iud removed a week ago today. My iud was halfway out of my cervix , it shifted so they took it out! I didnt spot at all after they took it out and i've been feeling so much better since. According to eve my estimated ovulation day was the 17th. my period was april 6-13th. ovulation window 14-21. We had unprotected sex on the 15,16,17 and he finished in me on the 17. I just randomly started spotting and having light cramps? is this normal?? i'm not really use to having a "normal cycle" since it was always irregular on my iud.
