Withdrawal bleeding post IUD?

I got my Kyleena IUD removed on the 8th and started bleeding yesterday (10th), however, it was very light and the blood was brown. Today it is now bright red like period blood and a full flow. I put a tampon in this morning and within a few hours I had bled through it. Is this normal for withdrawal bleeding? I’m actually supposed to start my period in 4 days (if it were to follow my same cycle I had with the IUD). I know the drop in hormones causes withdrawal bleeding but I’ve only seen where the bleeding should be very light like spotting (like what I had yesterday). I’ve also been cramping like I would if I were on my period. Can someone tell me if this is normal 😭
