Implantation?

April
8 days DPO & light brown appeared on the toilet paper when I used the restroom. 
Little backstory...
Third round of 50mg clomid. This month at the follicle study there appeared to be a 28mm follicle, doc thought it may be a blood cyst. That being said, I haven't had any of the symptoms that he explained to us. And at the end of our long chat at the appt with him he said "call me in 2 weeks when you're pregnant"
1st cycle was 28 days. 2nd cycle was 25. And today I am at CD 20.
I know I might be grasping at straws to think this might be a result of implantation. But I also have a hard time thinking I would start SO early. 
Trying to be hopeful.
