Pregnant?

Eve

Hey it’s me again! Still freaking out about this faded line. If I am pregnant it’s kinda to early to tell or maybe right on it. What weird is I have the IUD birth control but not only do I have this faded line but I am 4 days late on my period.. I had a little bleeding but it was brown and looked like implantation bleeding. It’s nearly impossible to get pregnant with the IUD right?
