What's going on! !!

Ok I was wrong! It wasn't my af. I had my iud removed on March 4 had no bleeding or spotting so had sex the 6th and just stared bleeding dark in color for like an hour and went away. I that it was af starting from getting 8 iud removed but just had my af 2 weeks prior to getting my iud removed. Or it was just late bleed from removing. I don't understand why I was bleeding? ?? What going on?? I have no bleeding at all now?? HELP PLEASE! !!
