Mirena IUD-please respond!

Hi guys! There are hundreds of posts on here already about the Mirena, which i realize, but I just want to get some advice. I am scheduled to get mine put in on August 8, which is about a week before my period would start. My doctor told me that it would be easier for me to put it in during my cycle, but that she was fine with doing it sooner if I was ready. I’m having anxiety about it now, so I am just wondering if it would be worth it to reschedule my appointment? I do have a relatively high pain tolerance, but I know it will still hurt like a bitch, lol. Did any of you get it put in around the same time during your cycle? I would love to hear about the pain and the amount of bleeding afterwards so i can prepare myself.
