Paraguard IUD

Recently I made the decision to get rid of the Nexplanon and get the Paraguard IUD. I hated the Nexplanon I was always moody, spotting or on my period, had terrible acne, etc. that's why I decided to go with a hormone free option. I'm a little concerned because I got the IUD inserted on Monday and I started my period on Wednesday even though I just had my period roughly two weeks ago. Is it normal that I started my period so quickly after getting the IUD? Should I be worried?
