Copper IUD/also TMI picture

So I’ll try to make this as short as possible, but I got the Copper IUD inserted in 2011, have lived it ever since. On Monday, two days ago, I got into an ATV accident and the handle bar of the ATV hit my pubic bone. I’ve had slight cramping on and off since, but it’s also ovulation time and I always cramp then. I woke up today and there was streaks of blood in my discharge, some bright red and dark brown, it has happened twice now. It’s hard to tell if my strings are in place because it hurts really bad to crouch into that position and I have a big bruise there. Should

I go to the ER or wait until my appointment tomorrow morning? Following photos go in order of today, the. Yesterday, the last one is hours after accident on Monday.
