Advice please?

I'm on cd 42 or cd 11. I have no idea. I miscarried last month on the 2nd. Found out on the 11th. The bleeding I had was like a really heavy period but last 5//6days and spotted a few after that. Well I suppose to get my period Sept 4th and it came Sept 2nd but it was lots of brown blood. I had a brief spotting of pink brown but that's it. Only lasted 2days and I spotted some only after sex for 2days after. We are TTC, I got w positive opk on August 29th so we BD. I've had faint lines. I feel like I'm going crazy. I'm tired of testing. I see faint lines on the morning first response and the morning blue dye.
