Pregnant?

So I’m on birth control (iud) and hadnt had my period in 7 weeks. Knew it was a normal side effect but I had a test left from my last pregnancy scare (which prompted me to get the IUD lol). So I decided to test this morning just to be safe and got this

Is the positive line supposed to look kind of blurred like that? Is it invalid? Faulty test? Or is it just a positive ? I’m freaking out
