What is going on?! 12dpo faint FRER??

I've been getting lines like these since yesterday morning. They're a little more clear in person, they show up in right away, and I am pretty sure they're pink. I thought it was my FRER box but the pic I posted is Answer brand and same line showed up immediately. 
I just think it's not a good sign since I'm 12 dpo and its sooo faint. And not getting darker. I had a miscarriage last month and I know I ovulated, and 3 days ago my tests were snow white with no second line at all. Even after 10 minutes. 
I need hope! I started my progestin yesterday. Trying to stay neutral but I want it so badly 😞
