IUD, symptoms but no proper bleeding?

Eva

I've had my IUD inserted in early april and I'm generally very happy with it.

But right now I'm at day 51 of my cycle and I had brown discharge two days ago. I feel weak, ate over half a plate of chocolate yesterday and I get cramps every now and then but I'm kind still kind of freaking out right now that I might be preg so I'm gonna call my doctor today 😠😧
