half positive???

Kristen

So I have gotten a bfp! actually it's like my 10th, but I've been watching the lines get darker over the past 4 days. what gets me is that the positive line is half dark and half light. I have missed my period and am having basic symptoms like really tired and swollen boobs. has anyone else had this? I haven't tried another type of test yet, should I?

what do you girls think? p.s. I'm putting it in the faint lines cause of the weirdness, mods please switch if needed.
