Paragard IUD

Patient: I am a 21yr old female who has not had any children. I got my Paragard inserted on Monday and all week I had cramping and a small amount of spotting. But it was getting better as the week went on. Then on Saturday, my husband and I had sex and I started lightly bleeding (more than spotting) and have had terrible cramps. I felt for my strings and I swear my cervix felt swollen (Like a bulb try to push out). Bow everything ‘feels’ normal. But I am still bleeding and having moderate cramps. Is this normal??
