8 DPO and depressed

I was trying to be stress free this cycle and nope! That didn't happen! I spotted at 3dpo, 5dpo, and 8dpo. The 3 could have been ovulation and I thought 5 maybe could have been implantation, but at 8 I feel like something's wrong.......... I did everything I could have done and don't feel pregnant or have out of the ordinary symptoms. I just feel depressed. If it was a failed cycle fine but the spotting (if I'm not) is not good!
