Pregnancy test line progression HELP!!!!

I had a chemical pregnancy on July 14th. On Wednesday at 11DPO I got a faint test which I thought was an indent line. I am also on progesterone supplements I started those on 3DPO. But my doctor thinks I miscarried because of luteal phase defect. But prescribed me progesterone supplements.  

Last night around 7pm I retested and the line got darker so I know it’s not an indent line.

This morning around 6:10 am i tested and the line is the same as last night and my bbt temp dropped so I am SCARED!!!!

Someone please give me some hope
