Implantation bleeding? Too early?

Han

My husband and I BD last night. My highest fertal day..

When I went to the restroom after this is what I had....

We have been ttc since july so I'm hoping it may be from August.Minor crampy the past few days, I took a test yesterday morning, negative, my period last month was late and short with no symptoms.. My cycle shouldn't start Untill the 24th of the month.

Any idea's what this is? Sorry for the picture..
