Is this too dark to still be trigger?

M

Hello I am looking for some info or similar experiences. I am 6dp5dt and 13 days past trigger and got a very clear line this morning. In my last two failed transfers I had a line that then faded because I believe it was the trigger shots. However, I don’t believe the line would be this dark if it was still the trigger at this point? Has anyone had a similar experience? Thanks so much for any info!
