AF or implantation bleeding?

Darcee
I'm on cycle day 23 and I was checking my cervix and CM and I had blood and a clot on my finger. I know TMI. So I waited until I got out of the shower to see if I was still bleeding and I was. My husband and I have TTC since I came off of my BC last month. 
I just went to the bathroom and now I'm not bleeding. I took out my tampon and it was just brown. Is this AF early or implantation bleeding? I left the tampon out and just used a pad to see if I bleed anymore. 
I haven't test yet and AF is not due for 12 more days. I don't know what to think.  I want to be a Mom so bad, but I didn't want to get my hopes up since we have only been TTC for just over a month. 
Any thoughts are welcomed.
