Feeling down. :(

Jaimee
So yesterday I was 11dpiui and hubby and I BD'd and afterwards there was a little blood mixed with semen. This morning; no blood whatsoever. No sign at all. Today at 12dpiui I took an hpt and it was bfn. So I guess I'm curious what people think the bleeding was? 
I read that it could be 
1) implantation bleeding 
2) AF spotting; and on her way 
3) bleeding because the cervix has extra blood flow to it during early stages of pregnancy. 
I'm assuming AF is on her way. But I don't have any symptoms at all. They all went away at 10dpiui. I had breast tenderness, nipple soreness, fatigue, heartburn, light cramping, headaches, and moodiness.
