Anyone have any experience with this?

I’ve known for about a week that I am pregnant, but my line is still faint. I’m on progesterone, which I didn’t start until I got a positive test. I had light spotting that looked a lot like implantation bleeding on Wednesday, which I thought was weird, and my lines are still faint.

I’m pretty convinced this is going to end in a chemical pregnancy, but does anyone else have any experience with a similar situation?
