Help me ease my mind, please!

We've been ttc for 10 months and I'm on the first round of clomid with progesterone. I got a faint positive at 9dpo and I have tested every morning and night since and they have been gradually getting darker, but today's test was the same as yesterday's. I'm so paranoid that the line is going to start going away and I'll have a chemical pregnancy. I also got my hcg checked at 10 dpo and it was 50. I haven't done my follow up test yet. I'm at 12 dpo today. Anyone have any advice?

Thanks!
