Recent Copper IUD insertion and bleeding after sex

Hello. I’d like to start off by saying I plan on contacting my doctor tomorrow but just wanted other people’s thoughts tonight and see if this is normal. I had my iud inserted last Monday, and last night was the 2nd or 3rd time we had had sex with the iud. This morning I experienced some blood afterwards from I am assuming last night when we had sex and it has continued into today. It’s not heavy, but I am a little crampy. It’s hard to tell if it was related to sex or just a coincidence and I started early? Any thoughts? Normal or nah? Thanks in advance
