Getting Darker each day?!?

10dpo and 3 to 4 days until AF. Took the first one on 6/26 and I think they are getting darker each day but I might be basis :) We have an appointment with an <a href="https://glowing.com/glow-fertility-program">IVF</a> doctor tomorrow that I set up a month ago so very ironic timing. Let me know your thoughts. I know I should wait until my missed period but the wait was killing me :)
