Evap or start of bfp?

Alicia
I had a miscarriage first week of September and we started ttc soon as a stopped bleeding. I ovulated on the 21st (positive opk) so I'm 10 dpo and i took a test yesterday and thought it was an evap. But took one this morning i thought i seen a line at the 3 minute mark. So i watched it and it got thicker and dark this picture is after a little while. Couldn't get the line to show up on the picture till now.
