Implantation bleeding? After IUD removal a week ago

So I got my IUD removed right around the time I was ovulating about 9 days ago and then the day after that I had a super heavy two day period and then no more bleeding. The last two days I’ve been having a tiny bit of spotting as well as some strange kinda cramps, some GI symptoms and really sore boobs on the sides. I’m wondering if it might be possible to be having implantation bleeding right now? Just looking for some thoughts and similar stories or anyone who ended up pregnant immediately after getting the IUD out. Oh and yes I was having unprotected sex before getting the IUD out and after.
