Any insight

To point out I have the mirena I’m not actively trying I’m using this forum to see what people think.

Let me start by saying, I’ve felt off for the last week or so.

Two weeks ago I spotted for less than a day, very light pink assumed a period was coming and since I’m on the mierna they’re very “spotty” no pun intended.

When I say less than a day I mean two wipes maybe three.

Last week I began feeling ridiculously sluggish and tbh kinda cranky.

Today my breast are warm and my nipples are excessively sore. Like SORE! They even hurt in the shower!

I went to the closest store and grabbed a test.

I know , I know don’t use blue dye however when I had my first child and only I used a blue clear blue and it worked perfect for me. However this is confusing to me it looks positive but it’s so faint I truly just don’t know. Any insight would be wonderful. One photo taken directly after the duo and the other about 5 minutes later.
