Mirena IUD bleeding

Hellooo, so I am a panicker big time and I just need some guidance 😂 so I got the mirena coil inserted on the 19th of September, I had spotting for a day or two then absolutely nothing, about 9 days after having it inserted I had these awful awful cramps and really heavy bleeding that is still happening, cramps not so much, I understand bleeding is to be expected and I think I might have been due my period around about now, could that be making the bleeding heavy?? is this normal bleeding or does it seem like a lot? And will bleeding be this heavy for 3-6 months? 🥺 I’m so sorry for the pictures I just dunno what to think as normal, thank you for your help 💖
